Question

factorize 5x^2-7x-12​

Answer 1

Step-by-step explanation:

5x^2 - 7x - 12 = 0

=> 5x^2 - (12-5)x - 12 = 0

=> 5x^2 - 12x + 5x -12 = 0

=> x (5x - 12) - 1 (5x - 12) = 0

=> (5x-12) (x-1) = 0

either 5x - 12 =0

=> x = 12/5

or x-1 = 0

x= 1

Answer 2

$5 {x}^{2} - 7x - 12$

$5 {x}^{2} - (12 - 5)x - 12$

$5 {x}^{2} - 12x + 5x - 12$

$x(5x - 12) + 1(5x - 12)$

$(5x - 12)(x + 1)$
