Factorize (6x^2 + 7x – 20)

A.
(6x – 5)(x + 4) 
B.
2(3x5)(x+2) 
C.
(3x+4)(2x5) 
D.
(3x4)(2x+5)
Correct Answer: Option D
Explanation
(6x^2 + 7x – 20)
= (6x^2 + 15x – 8x – 20)
= (3x(2x + 5) – 4(2x + 5))
= ((3x – 4)(2x + 5))
Factorize (6x^2 + 7x – 20)
(6x^2 + 7x – 20)
= (6x^2 + 15x – 8x – 20)
= (3x(2x + 5) – 4(2x + 5))
= ((3x – 4)(2x + 5))
