Find the square. 1) (w - 14)2 A) 196 w2 - 28 w + 196 B) w2 - 28 w + 196 C) w + 196 D) W2 + 196 Simplify the expression. Use positive exponents. Assume variables represent nonzero real numbers 2) (-5p ) 2 ( - 5p) 8 A) -51010 B) 5p C) 25p 10 D) 51010 Factor as completely as possible. If unfactorable, indicate that the polynomial is prime. 3) 10z2 + 11z - 6 A) (2z + 3)(5z - 2) B) (10z +3)(z - 2) C) (2z - 3)(5z + 2) D) prime Factor completely. 4) 27a4 - 4862 A) 3(3a2 - 4b) 2 B) 3(3a2 + 4b) 2 C) 3(3a2 +4b)(3a2 - 4b) D) Prime Factor the polynomial. 5) xa + 3a - xt - 3t A) (x - 3)(a + t) B) (x - t)(a +3) C) (x + a)(3 - t) D) (x+3)(a - t)
