Question

Find the value of ( 2A - B + C )​

Answer 1

Step-by-step explanation:

11x^-2y^+10xy(11square-2ysquare+10xy)

Answer 2

Answer:

11x²- 2y²+ 20xy

Step-by-step explanation:

A= 4x²-5y²+7xy

B= -3x²+8y²-4xy

C = 16y² -8xy

We have to find, 2A -B +C

=> 2(4x²-5y²+7xy) -(-3x²+8y²-4xy)+ (16y²- 8xy)

=> 8x²- 10y²+ 14xy+3x²-8y²+ 4xy+16y²-8xy

=> 8x²+3x² -10y²-8y²+16y² +14xy+4xy-8xy

=> 11x²-2y²+20xy
