Exercise 70 Page 365

Rewrite the given expression so that it is easier to make groups.

( x^2+2x+4 )(4y-3z)

Practice makes perfect

To factor by grouping, we will take the greatest common factor of the first three terms and the greatest common factor of the last three terms.

4x^2y+8xy+16y-3x^2z-6xz-12z

Factor out 4y

4y(x^2+2y+4) - 3x^2z-6xz-12z

Factor out -3z

4y(x^2+2x+4) -3z( x^2+2x+4)

Factor out ( x^2+2x+4 )

( x^2+2x+4 )(4y-3z)
