Subtract 8y2 – 3x2 + 2x + 3y from the sum of 2x2 + 3y and 5x2 + 3x. Also, find the value of the

expression obtained when x = -1 and y = -2.

Answer:

Answer of the 1st part attached in the Photo

2nd Part -

Equation obtained = 4x²+ 6y +5x -8y²

Put (x = -1) AND (Y = -2) =

4(-1)² + 6(-2) +5(-1) -8(-2)²

= 4 -12 -5 -32

= -45 Ans
