Question

3x square -x -4=0 factories​

Answer 1

Answer:

$3x ^{2} - x - 4 = 0 \\ \\ = > 3x ^{2} - (4 - 3)x - 4 = 0 \\ \\ = > 3x ^{2} - 4x + 3x - 4 = 0 \\ \\ = > x(3x - 4) + 1(3x - 4) = 0 \\ \\ = > (3x - 4)(x + 1) = 0 \\ \\ either \: 3x - 4 = 0 \\ \\ = > x = \frac{4}{3} \\ \\ or \: x + 1 = 0 \\ \\ = > x = - 1$
