2 X + 5 ka whole square​

Answer 1

Heya❤

$(2x + 5) {}^{2} \\ = (2x) {}^{2} + 2(2x)(5) + (5) {}^{2} \\ = 4x {}^{2} + 20x + 25....(the \: equation) \\ = 4x {}^{2} + 10x + 10x + 25 \\ = 2x(2x + 5) + 5(2x + 5) \\ = (2x + 5)(2x + 5) \\ \\ now..$

$2x+5=0$

$2x = -5$

$x= \frac {-5}{2}$

$2x+5=0$

$2x = -5$

$x= \frac {-5}{2}$

Hope it helps you
