Question

please answer fast please​

Answer 1

Explanation:

$12x {}^{2} + 51x + 12 = 0$

$12x {}^{2} + 48x + 3x + 12 = 0$

$12x(x + 4) + 3(x + 4) = 0$

$(12x + 3)(x + 4) = 0$

$3(4x + 1)(x + 4) = 0$

Therefore,

$x = \frac{ - 1}{4}$

OR

$x = - 4$

Answer: x = -1/4 or x = -4

Answer 2

Answer:

12x²+51x+12=0

12x²+48x+3x+12

12x(x + 4) +3(x+4)

(12x+3) (x +4)

12x+3=0

12x = -3

x= -3/12

x = - 1/4

next

x+4=0

x= - 4
