Question

Simplify with the help of formula :
25x² - 10x (5x - y) + (5x - y)²​

Answer 1

Answer:

(5×+(5×-y))^2

Step-by-step explanation:

(5×)^2-2(5x)(5×-y)+(5x-y)^2

(5×+(5×-y))^2

Answer 2

Answer:

Hope it helps :)

Step-by-step explanation:

we know that $(a-b)^2=a^2-2ab+b^2$

So,

$= 25x^2-50x^2+10xy+((5x)^2-(2*5x*y)+(y)^2)\\\\\\=25x^2-50x^2+10xy+(25x^2-10xy+y^2)\\\\\\\=25x^2-50x^2+10xy+25x^2-10xy+y^2\\\\\\=-25x^2+10xy++25x^2-10xy+y^2\\\\\\=-25x^2+25x^2+10xy-10xy+y^2\\\\\\=y^2$
