Question

I tried it with different help and it still was wrong

Answer 1

we have

2x^2-26x-60

Find the roots of the quadratic equation

Complete the squares

so

Factor the leading coefficient

2(x^2-13x-30)

Now factor x^2-13x-30

we have that

x^2-13x-30=(x+2)(x-15)

so

2x^2-26x-60=2(x+2)(x-15)

the answer is

2(x+2)(x-15)
