(Lesson 2.) While if x = 2, the second factor will be 0. But if any factor is 0, then the entire product will be 0. Therefore, if x = −4 or 2, then. x² + 2x − 8 = 0. −4 or 2 are the solutions to the quadratic equation. They are the roots of that quadratic. Conversely, if the roots are a or b say, then the quadratic can be factored as (x ...

The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

Show him how to check his answer by 'plugging in' the value of the variable. For example, if your child is solving the equation 6 + x = 10 for x, he might come up with the answer 16. Have your child 'plug in' the value of the variable by replacing x with 16 in the original problem, to make 6 + 16 = 10.
