Hi,
*Note: quadratic equations may be solved by factoring directly, if possible, or by using the quadratic equation to solve.
.
5x^2-5x-100=0
.
Can we factor this simply and directly?
(5x ... a)(x ...b)
What are the common mutiples of 100?? 10*10, 2*50, 25*4
would any these combinations work to gve us the desired result?
.
5x^2-5x-100=0
(5x -25)(x + 4) = 0
(5x - 25) = 0
x = 5
or
(x + 4) = 0
x = -4
.
Using the quadratic equation
.
.
x = 50/10 = 5
or
x = -40/10 = -4
