Question

Can someone help me on math

Answer 1

Just plug in the given values for a and b, since hypotenuse is represented as c.
\[\Large a^2 + b^2 = c^2 \]
a= 2x^2 + y^2
b= 2xy
\[\large (2x^2+y^2)^2+ (2xy)^2 = c^2 \]

Square, and then take the square root

Answer 2

Thx but i still don't understand i don't do math well

Answer 3

You can treat the (2x^2+y^2)^2 as just two
\[\large (2x^2+y^2)(2x^2+y^2) = 4x^4+2x^2y^2+2x^2y^2+y^4\]
Combine like terms
\[\large 4x^4+4x^2y^2+y^4\]

Then just do \[\large (2xy)^2 = 4x^2y^2\]

Add the two together
