factor and solve
6d^2 + 2d = 10d + 35
Answered by Marth
The first step in factoring is to move everything to one side.

6d^2 + 2d = 10d + 35
6d^2 - 8d - 35 = 0.

However, I cannot find real roots for this equation. Are you sure you typed it correctly?

I checked it and that is how it is on the worksheet I couldn't get it to work out either

You can find irrational factors using the quadratic equation.

For ax^2 + bx + c, x = (-b +/- sqrt(b^2 -4ac))/(2a).

6d^2 - 8d - 35 = 0
d = (8 +/- sqrt(64 - 4(6)(-35)))/(2*6)
