The first three steps for solving the quadratic equation by completing the square are shown. Fill in the missing number in the last step.
9x2 +54x = 7
9(x2 + 6x) = 7
9(x2 + 6x + 9) = 7+

[15 points]find the quotient with the restrictions. (x^2 - 2x - 3) (x^2 + 4x + 3) ÷ (x^2 + 2x - 8) (x^2 + 6x + 8)

Worth 100 points need the answers asap first row -x^2 2x^2 (x/2)^2 x^2 x is less than 2 x is greater than 2 x is less than or equal to 2 x is greater than or equal to 2 second row -5 -5/2 4 5 •2 is less than x& x is less than 4 •2 is less than or equal to x & x is less than or equal to 4 •2 is less than or equal to x& x is less than 4 •2 is less than x& x is less than or equal to 4

Complete the conditional statement. if a + 2 < b + 3, then a < b b < a a – b < 1 a < b + 1
