Question

Simplify $$(6x^2 -5y)^2$$


A
36x4+60x2y+25y2
loader
B
36x2+60x2y+25y2
loader
C
36x4+60x2+25y2
loader
D
36x460x2y+25y2

Solution

The correct option is D $$36x^4 -60x^2y + 25y^2$$
$$(6x^2- 5y)^2$$
Using $$(a-b)^2=a^2-2ab+b^2 $$ we get,
$$(6x^2)^2-2(6x^2)(5y)+(5y)^2$$
$$=36x^4-60x^2y+25y^2y^2$$
