c.(3x2+2x-1)+(x2-5x+6)
d.2(x+2y-xy)+5(2x-3y+5xy)
a.(2x+8)+(4x-5-5y)
b.(3p+q)+(-2p-5q+7)
c.(3x2+2x-1)+(x2-5x+6)
d.2(x+2y-xy)+5(2x-3y+5xy)
= 6x -5y + 3
b) 3p + q -2p - 5q + 7
= p - 4q + 7
c) 3x² + 2x - 1 + x² - 5x + 6
= 4x² - 3x + 5
d) 2 (x + 2y - xy) + 5 (2x - 3y + 5xy)
= 2x + 4y -2xy + 10x - 15y + 25xy
= 12x - 11y + 23xy
