Question

solve using algebraic identities-4x^2-y^2/25(whoever will solve this fast and correct I will mark them as brainliest...note that it should be correct)​

Answer 1

Answer:

-16x^2+16xy-y^2 / 25

Step-by-step explanation:

-4x^2-y^2/25

First look on before divide 25

i.e. -4x^2-y^2 which comes under identity a sq. - b sq.

(a)^2-(b)^2 = a^2 - 2 (a) (b) + b^2

here,

(a)=(-4x)

(b)=(-y)

=(-4x)^2 - 2( -4x)(y) + (-y^2)

=(-16x^2) + 16xy - y^2

Now add divided by 25

The final answer is

-16x^2+16xy-y^2 / 25
