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...

First we need to rearrange so that it's all on one side of the equals sign:x² + 2x - 48 = 0 Now we have to find what will sum to make the coefficient of x (2) and multiplies together to get -48...

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...

You take the power of X down and multiply the term by it. Then you reduce the power of the term in X by 1.
