Question

Solve the following quadratic function by utilizing the square root method. y = 100 – x2

Answer 1

Answer:

x = ± 10

Step-by-step explanation:

To solve the equation let y = 0 , that is

0 = 100 - x²( add x² to both sides )

x² = 100 (I take the square root of both sides )

x = ± $\sqrt{100}$ = ± 10

Then solution is x = - 10, x = 10
