Factoring patterns Consider the equation 9x2- 12x +4= 0, which sets a quadratic expression equal tozero.Part AWhich, if any, special factoring pattern could be used in finding the factorization of theexpression?A. Perfect Square Trinomial of a sum: a? + 2ab + b² = (a +b)²B. Perfect Square Trinomial of a difference: a? - 2ab + b? = (a – b)²C. Difference of Squares: a2 - b = (a+ b)(a – b)D. Sum of Squares: a2 + b = (a + bi) (a - bi)%3DE.

Solutions with imaginary numbers should be entered as integeri or (fraction)i; e.g.-2i or x = 2i would be entered as r = {-2i,2i}, while an answer ofi would be entered as a = {-(1/2)i,(1/2)i}.
