Question

4 a square + 9 b square + 25 x square - 12 a b - 30 BC + 20 AC

Answer 1

Answer:

$(2a-3b)(2a-3b+10c)+25x^{2}$

Step-by-step explanation:

$4a^{2} +9b^{2} +25x^{2} -12ab-30bc+20ac$

⇒$4a^{2}-12ab+9b^{2} -30bc+20ac+25x^{2}$

⇒$(2a-3b)^{2} +25x^{2} +10c(-3b+2a)$

⇒$(2a-3b)^{2} +25x^{2} +10c(2a-3b)$

⇒$(2a-3b)(2a-3b+10c)+25x^{2}$
