Question

fatorando os polinomios de:

A) 4a+20ax=

B) ax-bx+ay-by=

C) x elevado a 2 y elevado a 2 - 1/9=

D) p elevado 2 - pm + m elevado a 2 /4=

Answer 1

$a) \ 4a+20ax=4a(1+5x)\\ \\ b) \ ax-bx+ay-by=x(a-b)+y(a-b)=(a-b)(x+y)\\ \\ c) \ x^2y^2-\frac{1}{9}=(xy+\frac{1}{3})(xy-\frac{1}{3})\\ \\ d) \ p^2-pm+m^2/4 \ ????$
