Bell RingerFind the GCF of 15x2y and 45xy2. 5xy 3*5*x*y 5 15xy none of the above
Factor 2x2 - 3xz - 2xy + 3yz. x(2x - 3z) - y(2x - 3z) x(2x - 3z) - y(2x + 3z) (x - y)(2x - 3z) (2x2 - 3xz) + (-2xy + 3yz) none of the above
Solve by factoring a2 - 3a - 4 = 0. a = 1, -4 a = -1, -4 a = -1, 4 a = 1, 4 none of the above
Factor 12x2 + 22x - 14. (2x + 1)(3x + 7) (2x - 1)(3x - 7) (2x - 1)(3x + 7) (2x + 1)(3x - 7) none of the above
Solve by factoring: 12x2 + 22x - 14 = 0. x = ½ and -7/3 x = -½ and 7/3 x = -½ and -7/3 x = ½ and 7/3 - none of the above
