A portion of the Quadratic Formula proof is shown. Fill in the missing statement. Statements Reasons x squared plus b over a times x plus the quantity b over 2 times a squared equals negative 4 times a times c all over 4 times a squared plus b squared over 4 a squared Find a common denominator on the right side of the equation x squared plus b over a times x plus the quantity b over 2 times a squared equals b squared minus 4 times a times c all over 4 times a squared Add the fractions together on the right side of the equation the quantity x plus b over 2 times a squared equals b squared minus 4 times a times c all over 4 times a squared Rewrite the perfect square trinomial on the left side of the equation as a binomial squared ? Take the square root of both sides of the equation x plus b over 2 times a equals plus or minus the square root of the quantity b squared minus 4 times a times c end quantity, all over 4 times a squared x plus b over 2 times a all squared equals plus or minus b squared minus 4 times a times c, all over 4 times a squared all squared the square root of x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 4 times a squared x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 4 times a squared

I don't know if this is right

Part 1) x=3

Part 2) x = −1.11 and x = 1.11

Part 3) 105

Part 4) a = −6, b = 9, c = −7

Part 5) x equals 5 plus or minus the square root of 33, all over 2

Part 6) In the procedure

Part 7) -0.55

Part 8) The denominator is 2

Part 9) a = −6, b = −8, c = 12

Step-by-step explanation:

we know that the  formula to solve a quadratic equation of the form  is equal to Part 1) in this problem we have  so substitute in the formula Part 2) in this problem we have  so substitute in the formula Part 3) When the solution of x2 − 9x − 6 is expressed as 9 plus or minus the square root of r, all over 2, what is the value of rain this problem we have  so substitute in the formula therefore Part 4) What are the values a, b, and c in the following quadratic equation?−6x2 = −9x + 7in this problem we have    so Part 5) Use the quadratic formula to find the exact solutions of x2 − 5x − 2 = 0.In this problem we have    so substitute in the formula therefore   x equals 5 plus or minus the square root of 33, all over 2Part 6) Quadratic Formula proof we have  Divide both sides by a  Complete the square  Rewrite the perfect square trinomial on the left side of the equation as a binomial squared Find a common denominator on the right side of the equation Take the square root of both sides of the equation Simplify the right side of the equation Subtract the quantity b over 2 times a from both sides of the equation Part 7) in this problem we have     so substitute in the formula therefore The other solution is Part 8) in this problem we have  so substitute in the formula therefore The denominator is 2Part 9) What are the values a, b, and c in the following quadratic equation?−6x2 − 8x + 12in this problem we have  

so
