Now completing the square.

(x+5)² = 16 is the rewritten equation... For first question btw.
For the solutions to the equation -

x = -1,-9 is the solution, for the second question.
Nasser is making 80 flapjacks
1800g / 225g x 10=80
Multiply everything in the second parenthesis by x.
-3x^3 + 3x^2 + x
Multiply everything in the second parenthesis by 2.
-6x^2 + 6x + 2
Combine these two equations together.
-3x^3 + 3x^2 + x - 6x^2 + 6x + 2
Combine like terms.
-3x^3 - 3x^2 + 7x + 2
Hope this helps!
