Question

– Efetue as seguintes subtrações de polinômios:
a) (44x² - 34x + 10) – (52x² - 17x – 21) =
b) (96a – 63b + 42c) – (75a– 51b + 65c) =

Answer 1

Resposta:

$\left(44x^2-34x+10\right)-\left(52x^2-17x-21\right)\\\\44x^2-34x+10-\left(52x^2-17x-21\right)\\\\44x^2-34x+10-52x^2+17x+21\\\\-8x^2-17x+31$
