Question

What are the solutions of the quadratic equation below?
2x^2 - 8x - 42 = 0

Answer 1

have answer choices

Answer 2

2x^(2)-8x-42=0

Factor out the GCF of 2 from each term in the polynomial.
2(x^(2))+2(-4x)+2(-21)=0

2(x^(2)-4x-21)=0

2(x+3)(x-7)=0

x=-3, x=7

Answer 3

yes it was, thankyaaa!
