Question

factorize 8(x+1)^2 + 2(x+1)(y+2) - 15(y+2)^2​

Answer 1

Step-by-step explanation:

8(x+1)² + 2(x+1)(y+2) - 15(y+2)²

= 8( x²+2x+1²) + 2(xy+2x+y+2) -

15(y²+2y+2²)

= 8x²+16x+8 + 2xy+4x+2y+4 - 15y²-30y-60

= 8x²-15y²+2xy+16x+4x+2y-30y+4-60

= 8x²-15y²+2xy+20x-28y-56

That's your answer. I hope it will help you.
