Question

Solve the following using formula method 3x² - 10x = - 7. *​

Answer 1

Answer:

$3 {x}^{2} - 10x = - 7 \\ \\ = > 3 {x}^{2} - 10x + 7 = 0 \\ \\ = > 3 {x}^{2} - (7 + 3)x + 7 = 0 \\ \\ = > 3 {x}^{2} - 7x - 3x + 7 = 0 \\ \\ = > x(3x - 7) - 1(3x - 7) = 0 \\ \\ = > (3x - 7)(x - 1) = 0 \\ \\ either \: 3x - 7 = 0 \\ \\ = > x = \frac{7}{3} \\ \\ or \: x - 1 = 0 \\ \\ = > x = 1$
