The graph with equation y= x^3 - 6x^2 + 11x - 6 intersects the x axis at 1, find the other 2 points at which the graph intersects the x axis

the equation: x 3 - 6x 2 + 11x -6 Becasuse it intersects at the x axis, y=0 so we set the equation equal to 0. x 3 - 6x 2 + 11x -6 =0 we know it intersects the x axis at 1 and so (x-1) is a factor of that eq...

If 2x + y = 13 and 3x - y = 12, what are the values for x and y?

To solve these simulataneous equations we need to use substitution :If 2x + y = 13 then y = 13 - 2xTherefore 3x - y = 12 can be rewritten as 3x - (13 - 2x) = 12We can expand these brackets and solve for x :3...
