Step 1Factorization

Choose the complete factorization of \(4x^{2} - 8x - 60\).

a)2(x + 3) (x - 5)

b)\(4(x^{2} - 2x - 15)\)

c)(2x + 6) (2x - 10)

d)4(x + 3) (x - 5)

Step 2 Solution

\(4x^{2}-8x-60\)

\(=4(x^{2}-2x-15)\)

\(=4(x^{2}-5x+3x-15)\)

=4(x(x-5)+3(x-5))

=4(x-5)(x+3)

Step 3 Answer

Option d is correct option.
