(2x+9)² = (2x+9)(2x+9) Use FOIL to expand these brackets: First - (2x+9)(2x+9) --> 4x² Outside - (2x+9)(2x+9) --> 4x² + 18x Inside - (2x<...

Firstly we need to get all the x's on one side and the numbers on the other side. So if we add 2 to both sides we get 5x > 3x + 13. Now as we want the x's on the right hand side, we need to subtract bo...

Supposing we have two equations x+2y=5 and 3x-y=10 and we want to find x and y we can use the following techinque. Multiply both the RHS and the LHS of the second equation by 2, giving us 6x-2y=20. Then a...

Divide the length of the opposite side by the length of the adjacent side
