Factoring

What is the first step when factoring polynomials?

• Find the GCF

• List all the terms

• Make the X and fill in the top and bottom

• Multiply a and c

Solve for X:

(x-5)(x+6)=0

• {5,5 }

• { -5,-5 }

• { -5,-6 }

• {5,-6 }

What are the zeros?

• x= 0 and x= -4
• x= 0 and x= 4
• y= 0
• x= 2

What is another way to say "where a function crosses the x-axis"?

• x-intercept
• zero
• root
• all of these.

.How many zeros does this parabola have? 

• 3
• 2
• 0
• 1

What are the roots of the function
f(x)= (x - 2)(x + 3)?

• x = - 2 or x = 3
• x = 2 or x = -3
• The are no real roots
• x = 2 or x = 3

What are the solutions of this graph?

• -2 and 3

• -1/2 and -6

• -2 and -6

• 3 and -6

What are the solutions?

• 0 and 8
• -2 and -4
• 3 and -1
• 2 and 4

What is another word that describes the zeroes of a quadratic function?  

• y-intercepts
• vertex
• x-intercepts
• maximum

How many solutions does this function have?

• two

• one

• all real numbers

• no real solutions
