Question

Qual a forma reduzida de (2x+1)×3x=5×(x-4)+20 3

Answer 1

$(2x + 1) \times 3x = 5 \times (x - 4) + 20 \\ 6 {x}^{2} + 3x = 5x - 20 + 20 \\ 6 {x}^{2} + 3x - 5x = 6 {x}^{2} - 2x \\ 2x \times (3x - 1)$

Answer 2

(2x+1)×3x=5×(x-4)+20
6x^2 +3x=5x-20+20
6x^2 +3x-5x
6x^2 - 2x--->fatorar

2x. (3x-1)--->>>essa é a resposta
