Factor Review Algebra B

How many Terms? Two Factor out GCF Difference of Squares: Both terms square separated by minus

How many Terms? Three First factor out GCF if there is one Check if you can factor more Remember: Multiply to last term add to middle. ax2+bx+c=( + )( + ) ax2-bx+c = ( - )( - ) ax2 bx-c = ( + )( - ) Use Guess and check or Split the middle term

How many Terms? Three Guess and check

How many Terms? Three Split the middle term Multiply a with c (6)(-20)=-120 Find 2 numbers that multiply to answer and add to b -15 and 8 Now split the middle Next factor by grouping

How many Terms? Four Factor by grouping Make sure the two groups are separated by a + Factor the GCF from each group Factor the common binomial
