Determine the factored form of each polynomial.

LO: SWBAT factor quadratic polynomials of the form
ax²+ bx + c with a GCF.

DOL: Given 5 problems, students will correctly factor
expressions in the form of ax² + bx + c with or without a GCF at least 4 of 5 questions.

ALGI.10E - Factor, if possible trinomials with real factors in the form ax2+ bx + c, including perfect square trinomials of
degree two.
