Question

Agrupe os termos que possuem fator comum e fatores as expressões.
A) 2ײ+2×y-3×-3y
B) 3ab-4a²b²+a³-12b³

Answer 1

A---> 2X^2+2XY-3X-3Y
        2x(x+y)-3(x-y)
        2x(x+y)-3x+3y
        2x(x+y)-3(x+y)
        (x+y)(2x-3)
B---->3ab-4a^2b^2+a^3-12b^3
         3ab+a^3-4a^2b^2-12b^3
        a(3b-a^2)-4b^2(a^2-3b)
        a(b+a^2)-4b^2a^2=12b^3
         a(3b+a^2)-4b^2(a^2+3b)
             (3b+a^2)(a-4b^2)
