the function y=2x^2+6x-8. which value is a solution to tyhe equation 2x^2+6x-8=0

Question

There are many ways to solve quadratic equations, such as factoring,taking square roots, completing the square, and using the quadratic formula. Factoring involves setting each factor equal to zero and solving each factor. 

Answer 1

If you solve by factoring we have

 

2(x^2+3x-4)=0

2(x+4)(x-1=0

(x+4)= 0 x=-4

x-1=0 x=1
