How do you expand brackets in a quadratic equation?

To expand the brackets in a quadtratic equation you should multiply whatever is outside the bracket by that which is inside the bracket. For example: 2(x+3) First multiply the first part of the bracket with whatever is outside the bracket: 2x Then multiply the second part of the bracket with whatever is outside the bracket: +6 = 2x +6
