Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. a^2-2a-224=0

{-14, 16}

Step-by-step explanation:

The coefficients of this quadratic are a = 1, b = -2 and c = -224.

Thus, the discriminant is b^2 - 4ac, or (-2)^2 - 4(1)(-224), or 900, whose square root is 30.

Thus, the roots (solutions) are

      -(-2) ± 30

x =  =  {-14, 16}

             2

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range
