9 = 2(2x + 4)2, 9 = 2(4x2 + 16x + 16), 9 = 8x2 + 32x + 32 How did the 16x come about?
The coordinates of the x-intercepts given are (-1,0) and (3,0). The y-intercept is 2.5. How do you create an equation in standard and vertex form with that info? I'm not sure what each...
how do i solve this?
While working on quadratic equations with students I have discovered a few techniques that are particularly effective. By far the most effective is to require the students to solve each one by all three methods ( factoring, completing the square and quadratic formula ) for each and every problem rather than solving it only by the easiest way and to require the graph for each and every one.... read more
