Algebra 1 B Final Review

Find the zeros.

• 0 and 4
• 0 and -4
• 0
• -4

True or false:
The solution, root, x-intercept, and zero of a problem are all the same thing.

• True
• False, because the solution and root are the same but the x-intercept and zero are different
• False, because the x-intercept and root are the same but the zero and solution are different
• False, they are all different

What are the solutions to this equation? (x-3)(x+2)=0

• x=3,-2
• x=-3,2
• x=2,3
• x=3,2

• √3
• ±√3
• -3
• No real solution

ax²+bx+c=0  is the standard form of a quadratic equation.

• True
• False

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3

• a = 4, b = -8, c = 3
• a = 4, b =-8, c =-3
• a = 4, b = 8, c = 3
• a = 4, b = 8, c = -3

What is the vertex of the graph?

• (2, 4)
• (3, -1)
• (0, 8)
• (4, 2)

What should you do first to solve this equation using quadratic formula?

x² + 6x - 13 = 3

• Get factored form

• Write down: a=1, b=6, c=-13

• Make it equal 0 by subtracting 3 on each side

• Type it all in a calculator.

Identify the 'a' value:
 y = 16x² - 8x - 24

• 16
• 8
• -8
• -24

Identify the 'b' value:
 y = 16x² - 8x - 24

• 16
• -8
• 8
• -24
