Question

solve: 3x²-10x- 4= - 12​

Answer 1

Answer:

3x^2-10x+8=0

3x^2-6x-4x+8=0

3x(x-2)-4(x-2) =0

(3x-4) (x-2) =0

x=3/4

x=2

Answer 2

Answer:

$3 {x }^{2} - 10x \: - 4 + 12 = 0 \\ 3 {x}^{2} \: - 10x \: + \: 8 \: = \: 0 \\ 3 {x}^{2} \: - \: 6x \: - 4x \: + \: 8 \: = \: 0 \\ 3x(x - 2) - 4(x - 2) = 0 \\ (3x - 4)(x - 2) = 0 \\ 3x - 4 = 0 \: \: x - 2 = 0 \\ x = \frac{3}{2} \: \: \: \: \: \: \: \: \: \: x = 2$
