Question

f(x) = (x2 – 3 x)(8 x + 3)
​

Answer 1

$x1= - \frac{3}{8} \\ x2 = 0$

Explicación paso a paso:

$f(x) = ( x2 - 3x)(8x +3)$

$0 = (x \times 2 - 3x)(8x + 3) \\ (x \times 2 - 3x)(8x + 3) = 0 \\ (2x - 3x)(8x + 3x) = 0 \\ - x(8x + 3) = 0 \\ - x = 0 \\ 8x + 3 = 0 \\ \\ x1 = - \frac{3}{8} \\ x2 = 0$
