Question

Which of the following are solutions to the quadratic equation? Check all that apply.

2x^2 + 7x - 14 = x^2 + 4

Answer 1

-9 and 2 are the correct choices here. So, A and F.

Hope this helps! (:

Answer 2

he solution of the quadratic equation is x=-9 and x =2

So (a) and (f) are correct option

Explanation:

We have given the equation
`2x^2+7x=14=x^2+4`

`x^2+7x-18=0`

`x^2+9x-2x-18=0`

`x(x+9)-2(x+9)`

Now taking (x+9) common

`(x+9)(x-2)=0`

x = -9 and x= 2 are the roots of the equation

So the solution of the quadratic equation is x=-9 and x =2

So (a) and (f) are correct option
