Question

e) (x2 - y) from (2x2 - 3y2 + xy)​

Answer 1

Step-by-step explanation:

First we need to find the value of x

${x}^{2} - y = 0 \\ {x}^{2} = y \\ x = \sqrt{y}$

Now let's substitute the value of x in the given equation

$p(x) = 2 {x}^{2} - 3 {y}^{2} + xy \\ p( \sqrt{y} ) = 2 ({ \sqrt{y} })^{2} - 3 {y}^{2} + ( \sqrt{y} \times y)$

$= 2y - 3 {y}^{2} + y \sqrt{y}$

This is the answer
