1.15x² -26x + 8
What's the question?
If you're asking for the roots, they're about 0.312 and 22.3
If you're asking for the derivative, it's 1.15x - 26
I need help solving this given equation for x.
0.7x - 2.5 = 2.3x + 2.2
Let's begin by multiplying both sides by 10. Whenever you multiply both sides by the same number, the outcome is unchanged.
7x - 25 = 23x + 22
Gather like terms
23x - 7x = -22 -25
16x = -47
x = -2.9375
That's an unlikely looking result, so let's check
LHS = 0.7 x -2.9375 -2.5 = -4.55625
RHS = 2.3 x -2.9375 + 2.2 = -4.55625
OK
