How do I solve the following problems??
1. Factor: 4x^2-100y^2

2. Factor: 3x^2+27

3. Solve 3x^2+9x=0

4. Solve 12^2+30x=-12

5. 9a(a+1)=4

6. Solve 16x^2=25

    1. Factor: 4x^2-100y^2
    use difference of two squares,

    2. Factor: 3x^2+27
    the common factor is 3.

    3. Solve 3x^2+9x=0
    factor and solve:
    x=0 or x=?

    4. Solve 12^2+30x=-12
    Factor out the 6, and then factor completely to solve for x:
    Hint: it's in the form
    (2x 1)(x 2)

    5. 9a(a+1)=4
    Expand, transpose everything to the left, and then factor.

    6. Solve 16x^2=25
    isolate variable:
    and solve for x.
