Question

solve the quadratic equation:{12x^2-13x- 4} with steps

Answer 1

$\huge\mathbb\red{απswer..}$

=12x^2-13x-4

=12x2 - 16x + 3x - 4

= 4x • (3x-4)+1 • (3x-4)

= (4x+1) • (3x-4)

Answer 2

$= {12x}^{2} - 13x - 4 \\ = {12x}^{2} - 16x + 3x - 4 \\ = 4x(3x - 4) + 1(3x - 4) \\ = (3x - 4)(4x + 1) \\ x = \frac{4}{3} or \frac{ - 1}{4.}$

hope it helps.......
