Question

Section 1.1

1. solve each equation by using the quadratic formula (what is this quadratic formula? Don't understand how this is done)

M² + 2m = 8

2. Solve each equation by using the quadratic formula

4 + 20x = 25x²

3. solve each equation by using the quadratic formula

2y² + 1 = 2y

4. Number solutions. Find b² - 4ac and the number of real solutions to each equation

9m² + 16 = 24m

5. ½ x² + x = 1

6. Find two real numbers that have a sum of 8 and a product of 2

Section 1.2

1. Writing a quadratic equation with given solutions. For each given pair of numbers find a quadratic equation with integral coefficients that has the numbers as its solutions.

-8, 2

2. Using the discriminant in factoring. Use the discriminant to determine whether each quadratic polynomial can be factored, then factor the ones that are not prime.

8x² + 6x - 27

3. Equations Quadratic in form

(3a + 2)² - 3(3a + 2) = 10

4. Find all real solutions to each equation

2x - 5√x + 2 = 0
