Question

Write the quadratic function in standard form that has two zeros where x = ‒2 and x = ‒5.

Answer 1

1) If x = -2 and x = -5 then the equation would be the product of 
(x +2) * (x +5) =
x^2 +7x + 10

2) If x = -2 and x = 0 then the equation would be the product of
(x + 2) * (x -0) =
x^2 + 2x = 0

3) If x = -2 and x = -2 then the equation would be the product of
(x + 2) * (x  + 2) =
x^2 + 4x + 4 = 0
