Step 1: Times out the brackets 12x + 8 = 12 -5x
Step 2: Gather all 'x' values on one side and all non-'x' values on the other (12x + 5x = 12 - 8) -> 17x = 4
Step 3: Divide by the number next ...

SohCahToa
 We use SohCahToa to figure out an unknown angle or side in a right angled triangle. In questions, you will see a right angled triangle and have either two sides given (so ...

Equation of this type should be seen as x²-SX+P=0, where S is the sum of the solutions, while P is their product. We have too find 2 numbers whose sum is S and product is P. In this example, we...

1. Identify a common denominator4(x +1)/12 + 3(2x + 5)/12 (= 2)2. Expand both brackets(4x + 4)/12 + (6x +15)/12 = 23. Multiply out the denominator4x + 4 + 6...

Divide the term in x by 2 and then put it in the bracket which will be squared. The last term from that expansion needs to be adjusted for.
