Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. −5y^2 + 2y = −2

So before we can solve using the quadratic formula, we have to set the equation to zero. We can do that by adding 2 on both sides of the equation

Now we can use the quadratic formula, which is , with a=x^2 coefficient, b=x coefficient, and c=constant. We can form the equation as such:

Firstly, solve the exponents and the multiplications:

Next, do the addition within the radicals (these will be your exact solutions. but I'll solve for the decimal form as well.):

Next, solve for the rest on your calculator, and your answers will be (rounded to the thousandths) y = -0.463, 0.863

x= 149. 24+7=31. 180-31=149
