Question

Need help solving question 34 via expanding and simplifying thanks

Answer 1

34. The equation is given as

$(x+y)^2-x(2-y)$

Solving the equation by expanding and simplifying.

Use the identity,

$(a+b)^2=a^2+b^2+2ab$$x^2+y^2+2xy-2x+xy$$x^2+y^2-2x+3xy$

Hence the answer is

$x^2+y^2-2x+3xy$
