    Project # 1
    Work only equation: (a) x^ - 2x - 13 = 0 and (c) x^ + 12x - 64 + 0, but complete all 6 steps (a-f) as shown in the example.

    Project#2,
    Please select at least five numbers: 0(zero), two even numbers and two odd numbers. Make sure you organize into separate projects.
    The assignment must include all the math work required to answer the problems.
    The steps are:
    • Move the constant term to the right side of the equation.
    • Multiply each term in the equation by four times the coefficient of the x^ term.
    • Square the coefficient of the original x term and add it to both sides of the equation.
    • Take the square root of both sides.
    • Set the side of the equation equal to the positive square root of the number on the right side and solve for x.
    • Set the left side of the equation equal to the negative square root of the number on the right side and solve for x.

    Example: Solve x^ + 3x - 10 = 0
    X^ + 3x = 10
    4x^ + 12x = 40
    4x^ + 12x + 9 = 40 + 9
    4x^ + 12x + 9= 49
    2x + 3 = + 7
    2x + 3 = + 7 2x + 3 = - 7
    2x = 4 2x = -10
    x = 2 x = -5.
