Question

- 25 - x square - 10 x ​

Answer 1

Answer:

$\red { -25 - x^{2} - 10x }\green {= - (5+x)(5+x) }$

Step-by-step explanation:

Given -25 - x² - 10x

= - ( 25 + x² + 10x)

= - [ 5² + x² + 2×5×x ]

= - ( 5 + x )²

$\boxed {\pink { a^{2} + b^{2} + 2ab = (a+b)^{2}}}$

$= - (5+x)(5+x)$

Therefore.,

$\red { -25 - x^{2} - 10x }\green {= - (5+x)(5+x) }$
