Question

Write a quadratic equation that has the solutions: 4 and -7

Answer 1

y = ( x-4)(x+7)

Explanation:

When we know the zeros of the equation, we can write the equation in the form

y= a(x-z1) (x-z2) where a is a constant and z1 and z2 are the zeros (solutions)

y = a( x-4)(x--7)

y =a( x-4)(x+7)

Since its says write an equation, we can pick a and I will let a=1

y = ( x-4)(x+7)
