Hi,
20x2-13x-15 = 0
*Note: Using quadratic formula to solve for a equation in the form ax^2 + bx + c = 0
.
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
.
x+=+%2813+%2B-+sqrt%28+1369+%29%29%2F%2840%29+
.
x+=+%2813+%2B-+37%29%2F%2840%29+
.
x+=+-24%2F%2840%29=%28-6%2F10%29+=+-.6+
x = -.6
.
x+=+50%2F%2840%29=%285%2F4%29+
x = 1.25
