Factor 15x^3 - 5x^2 +6x-2 by grouping. what is the resulting expression

Match each equation to the ordered pair that represents one of its solutions. 3x + 2y = 6 -5x + y = -10 x ? 4y = 8 -6x ? 5y = 30 ordered pair equation (0, -6) arrowboth (0, 3) arrowboth (4, -1) arrowboth (1, -5) arrowboth reset next unit 2 - pretest
