For the next few problems, you'll be multiplying binomials.
When we multiply these binomials, we get
To enter the answer, you will enter only the middle and last term (for now, the x-squared won't change). So, for this answer, you would type in 5x, 6

Let's generalize (create a formula) for multiplying two binomials
When multiplied out, the "b" value for this quadratic expression is:
m+n
m-n
mn (m times n)
m/n (m divided by n)
When both the 9 and 5 are positive, what is true about the "b" and "c" values?
b and c are both positive
b and c are both negative
b is negative and c is positive
b is positive and c is negative
Let's generalize (create a formula) for multiplying two binomials
When multiplied out, the "c" value for this quadratic expression is:
m+n
m-n
mn (m times n)
m/n (m divided by n)
When the "bigger" number (9) is negative and the smaller number (5) is positive, what is true about the "b" and "c" values?
b and c are both positive
b and c are both negative
b is negative and c is positive
b is positive and c is negative
When the "bigger" number (9) is positive and the smaller number (5) is negative, what is true about the "b" and "c" values?
b and c are both positive
b and c are both negative
b is negative and c is positive
b is positive and c is negative
When both numbers are negative, what is true about the "b" and "c" values?
