12x2−7x−5

=12x2−12x+5x−5

=(12x2−12x)+(5x−5)

=12x(x−1)+5(x−1)

=(12x+5)(x−1)

Step-by-step explanation:

12x^2 -17x-5 = 0

x^2 -17/12x = 5/12

(1/2 × coeff of x)^2

(1/2 × 17/12)^2

(17/24)^2

289/576

x^2 -17/12x + 289/576 = 5/12 + 289/576

You may observe first part as perfect square.

solve futher and get your answer
