Factoring means to write as a product

Always look for a Greatest Common Factor 1st.

Factor 4x + 6y What is their greatest

common factor?

= 2( )2x

+ 3y

3y – 8xyFactor

What is their GCF?

= y( )3– 8x

2a3 – 6ab2

= 2a( )a2 – 3b2

2h2k + 2kFactor

What is their GCF?

= 2k( )h2+ 1

6uv + 9v2

= 3v( )2u

+ 3v

Let’s practice!!!Little Worksheet

(write PRIME if it cannot factor)

10.5 Factoring ax2 + bx + c when a = 1

What two numbers multiply to give you 8, but add to give you 6?

To FACTOR a trinomial means to write it as the product of two binomials.

Factor x2 + 6x + 8

What two numbers multiply to give you the last number…and add to give you the middle number?

(x + 2) (x + 4)

Write two sets of parenthesis and fill

in the numbers.

(x ) (x )

Factor x2 - 3x + 2

What two numbers multiply to give you the last number…

and add to give you the middle number?

(x - 2) (x - 1)

Ex: 1

(x ) (x )

Factor x2 - 2x - 8

(x - 4) (x + 2)

Ex: 2

Factor x2 - 5x - 14

(x - 7) (x + 2)

Ex: 3

(x ) (x )

Factor x2 - 16x + 64

(x - 8) (x - 8)

Ex: 4

(x ) (x )

Same thing as (x - 8)2

Factor x2 - x - 42

(x - 7) (x + 6)

Ex: 5

(x ) (x )

Solve the equation by factoring

x2 - 8x + 12 = 0

(x )(x ) = 0

x - 6 = 0 or x – 2 = 0

x = 6 or x = 2

Ex: 6

Solve the equation by factoringx2 - 7 = - 6x

(x )(x ) = 0

x - 1 = 0 or x + 7 = 0

x = 1 or x = -7

Ex: 7

x2 + 6x - 7 = 0
