Factor to solve
x2 –10x – 24 = 0
2. 5x2 + 18x + 16= 0 {slide and divide}
(x-12)(x+2) x = -2,12
X2 + 18x +80 (x+10)(x+8) x = -8,
X = -8/5 and -2

2. y = 2(x+1)2 – 4 2(x2 +2x+1) – 4 2x2 +4x-2 -2 = a(0+1)2 – 4 a = 2
3. Give general form of a parabola with vertex (-1,-4) and point (0,-2)
y = 2(x+1)2 – 4
2(x2 +2x+1) – 4
2x2 +4x-2
-2 = a(0+1)2 – 4
a = 2

3. Solve: 43(x-7) = 4 2(x-10) 4. 64x-7 = 16x-10 Ln e(x-2) = ln8
x-2 = ln8 x ≈ 4.079
6. log5(x-1) = 4
5 5
x-1 = x = 626
7. 52x-3 = 7
log log5

4. 8. Continuous compounded interest uses the formula: A = Pert
8. Continuous compounded interest uses the formula: A = Pert. You deposit $3000 in an account that pays 3% annual interest compounded continuously. What is the balance after 5 years?
A = 3000e(0.03·5)
A ≈

a. x b. x3 c. x4 d. -x4

6. Homework, copy problems first!
FOIL or multiply out
1. 2(x + 6) (x-9)(x +3)2
Solve by quadratic equation:
3. 6x x – 3 = x x + 5= 0
5. 4x x - 8 = x x + 9= 0
