Question

Fatore as expressões algébricas: a) x2 – xy b) 6x3 – 12x2 – 36 c) 5x2 + 3xy + 12x d) 13ab – 4a2b2 + 4a2b – ab2-

Answer 1

Resposta:

a. $x^{2} - xy =\\x (x - y)$

b.$6x^{3} - 12x^{2} - 36 =\\6 (x^{3} - 2x^{2} - 6)$

c. $5x^{2} + 3xy + 12x =\\x (5x + 3y + 12)$

d. $13ab - 4a^{2}b^{2} + 4a^{2}b - ab^{2} =\\ab (13 - 4ab + 4a - b)$
