Question

faxtorize- ab(c^2+d^2)-a^2cd-b^2cd​

Answer 1

Answer:

$ab(c^2 + d^2) - a^2cd - b^2cd$ $=(bc - ad)(ac - bd)$

Step-by-step explanation:

$ab(c^2 + d^2) - a^2cd - b^2cd$

$=abc^2 + abd^2 - a^2cd - b^2cd$

$=abc^2 - a^2cd - b^2cd + abd^2$

$=ac(bc - ad) - bd(bc - ad)$

$=(bc - ad)(ac - bd)$
