1 Quadratc Formula Completng the Square Systems Revew Sheet 1. Factor the polynomal completely. 6. Use the graph to approxmate the real zeros of the functon. 2. Fnd the real-number solutons of the equaton Fnd all zeros of the polynomal functon. 7. Factor the expresson Factor the expresson Wrte as the product of two factors:
2 no real-number soluton Wrte the expresson as a complex number n standard form Factor completely. Smplfy the expresson Solve for x
3 21. Solve by completng the square and and and and What are the zeros of the polynomal functon graphed below? 22. Use the quadratc formula to solve: Whch equaton(s) represent the graph below? I II III 24. x = x = x = x = Solve by factorng: I only II only I and II II and III Fnd the zeros of the functon. 26.
