a) 8a=16
Make into an equation = 0, then factor it:
Subtract 16 from both sides and you have:
8a - 16 = 0
Factor out 8
8(a - 2) = 0

2. Write the following as single powers.
a) y squared + y cubed
(y*y) + (y*y*y)

3. Expand the following.
a) x(x+2y)
Mult what's inside the bracket;
x^2 + 2xy

:
4. Expand the brackets in these expressions.
a) 2(x+3)+2(x+4)
2x + 6 + 2x + 8
4x + 14 Or 2(2x + 7), not sure what "expand the brackets" means
