Question

8x^2 - 50
Factor the polynomial
best answer gets medal

Answer 1

Find the greatest common factor of \(8x^2\) and \(50\), and then factor that out.

Answer 2

Basically start by looking at the coefficients. What can be factored out of both 8 and 50? The only thing i can think of is 2.

so you get 2(4x^2-50)

At this point, it's just a difference of squares a^2 - b^2 = (a+b)(a-b)

2(2x+5)(2x-5)

Always remember to keep the coefficient
