Question

(3x²-5х+5)×2/3＝2x²+5х-1

Answer 1

$(3x {}^{2} - 5x + 5) times frac{2}{3} = 2x {}^{2} + 5x - 1 \ 2x {}^{2} - frac{10}{3} x + frac{10}{3} = 2x {}^{2} + 5x - 1 \ - frac{10}{3} x + frac{10}{3} = 5x - 1 \ - 10x + 10 = 15x - 3 \ - 10x - 15x = - 3 - 10 \ - 25x = - 13 \ 25x = 13 \ x = frac{13}{25 } = 0.52$
