Question

solve the quadratic equation 3(x^2-4) = 5x​

Answer 1

Answer:

X=3 or X= -4/3

Step-by-step explanation:

$3 (x^{2} - 4) = 5x \\ \\ 3 x^{2} - 12 = 5x \\ \\ 3x ^{2} - 5x - 12 = 0 \\ 3x ^{2} - 9x + 4x - 12 = 0 \\ \\ \\ 3x(x - 3) + 4(x - 3) = 0$

$3x(x - 3) + 4(x - 3) = 0 \\ \\( x - 3 )(3x + 4) = 0 \\ \\ x = 3 \: or \: x = -4 \3$
