Document Summary
Please read the problems carefully and do all you are asked to do. You can use the back page as scratch paper and do the problems at the space provided. Your calculator model: (10pts) simplify to get an answer with non-negative exponents only. (a). (2s 2)5 = 25 s( 2) 5 = 32s 10 = 32 s10. 1: (10pts) multiply the polynomials. (a). (4x4y 7x2y3)(2 3x2y2) = = 8x4y 12x4y x2y2 14x2y3 + 21x2y3x2y2. = 8x4y 12x6y3 14x2y3 + 21x4y5 (b). (y 2)(y + 2)(y2 + 4) = (y2 4)(y2 + 4) = ((y2)2 42) = y4 16: (10pts) factor into polynomials with real coe cients. (a). x3 3x2 5x + 15. = (x3 3x2) + ( 5x + 15) = x2(x 3) 5(x 3) = (x2 5)(x 3) = (x + 5)(x 5)(x 3) (b). 6x2 7x 20 = (2x 5)(3x + 4) 1 pg score: (10pts) perform the operations and simplify your answer into lowest terms. (a).
