# Algebra1 Math Questions?!

**Question:**Algebra1 Math Questions?

So I don't understand my math homework, and really need help! My teacher didn't teach us ANY of this..

PS- ^(2) is supposed to be a power ( 3 to the second power.. etc.)

Answer as many as possible so I can teach myself!

1. What is the vertex of the graph of y= 1/2 (x + 6)^2 (^2 = exponent) -2

2. The axis of symmetry of the graph y = -(x - 3)^(2) + 5 = ?

3. What is the factored form of x^(2) - 3x - 28

4. The solutions to (x + 3)^(2) - 25 = 0

5. Which of the following shows x^(2) - 6x + 5 = 0 in the form (x - h)^(2) + k = 0

6. The graph of y = x^(2) - 2x - 3 intersects the x-axis at

7. The solutions to x^(2) - 6x - 27 = 0 are

8. The zeros of y = x^(2) + 8x + 7 are

9. Which of the following would complete the square for x^(2) + x?

a. 1/2 b. -1/2

c. 1/4 d. -1/4

a. 1/2 b. -1/2

c. 1/4 d. -1/4

**Answers:**

1) (6,-2) <--- coordinate point

2) y= 5

3) (x-7) (x+4)

4) x=2, x= -8

5)

6) intersects at -1 and 3

7) x= 9, x= -3

8) zeros at 1 and and 7

9) A, use the formula b/2a
