Question

(4X-1) (2x + 3) = 18 x - 4​

Answer 1

Respuesta:

$8{x}^{2} - 8 + 1 = 0$

Procedimiento:

$(4x - 1)(2x + 3) = 18x - 4 \\ \\ 4x(2x) + (4x)(3) - (1)(2x) - (1)(3) = 18x - 4 \\ \\ 8 {x}^{2} + 12x - 2x - 3 = 18x - 4 \\ \\ 8 {x}^{2} + 10x - 3 = 18x - 4 \\ \\ 8 {x}^{2} + 10x - 3 - 18x + 4 = 0 \\ \\ 8 {x}^{2} - 8x + 1 = 0$
