2x^2-16x+30=0

OpenStudy (mertsj):

1. Factor out the 2 2. Factor the resulting trinomial 3. Set each factor equal to 0 4. Solve each equation.

how

OpenStudy (mertsj):

1. Factor out 2

OpenStudy (anonymous):

2(x?

OpenStudy (mertsj):

\[2(x^2-8x+15)=0\]

OpenStudy (anonymous):

is that it?

OpenStudy (mertsj):

No. Now do step 2 as I outlined above. You do know how to factor I assume? Because you cannot solve quadratic equations by factoring if you don't know how to factor.

OpenStudy (anonymous):

2(x-3)(x+5)?

OpenStudy (mertsj):

That would give you -15 on the end and +2x in the middle.

OpenStudy (anonymous):

switch the signs?

OpenStudy (mertsj):

Try it and see if it works.

OpenStudy (mertsj):

Or am I getting that you don't know how to multiply two binomials using FOIL?

OpenStudy (anonymous):

no :(
