Answer 2

Answer

(a) $3p^5q-5p^2q^3$

$p^2q\times 3p^3-p^2q\times 5q^2\\=p^2q(3p^3-5q^2)$

(b) $9a^2b^2c^3-10a^2b^2c^2$

$a^2b^2c^2\times 9c-a^2b^2c^2\times 10\\=a^2b^2c^2(9c-10)$

(c) $pm-pl+pn$

$p\times m-p\times l+p\times n\\=p(m-l+n)$

(d) $20x^{15}y^{15}-15x^{12}y^{13}$

$x^{12}y^{13}\times 20x^3y^2-x^{12}y^{13}\times 15\\=x^{12}y^{13}(20x^3y^2-15)$

(e) $7x^3+7y^3x$

$7x\times x^2+7x\times y^3\\=7x(x^2+y^3)$

(f) $3x^2y^2+4y^2z^2+12x^2y^2z^2$

$y^2\times 3x^2+y^2\times 4z^2+y^2\times 12x^2z^2\\=y^2(3x^2+4z^2+12x^2z^2)$
