Question

b) 7xy - 3x + 4x =
c) 8y2 + 5y2 + 3 - 2 =
d) 12x²y + 4x - 12 + 8x²y + 5 =
e) 4a - 5b + 16a + 8 + b =
f) x(x + 2) =
g) 2y ( y-1) =​

Answer 1

b)

$7xy-3x+4x=7xy+x$

c)

$8y^{2} + 5y^{2}+ 3 - 2 =13y^{2} +1$

d)

$12x^{2} y + 4x - 12 + 8x^{2} y + 5 =20x^{2} y+4x-7$

e)

$4a - 5b + 16a + 8 + b =20a-4b+8$

f)

$x(x + 2) =x^{2} +2x$

g)

$2y ( y-1) =2y^{2} -2y$
