It is a simple linear equation in 's'. Its solution is the number that 's' must bein order to make it a true statement. The solution may be found like this:4s + 10 = 2s + 2Subtract 10 from each side of the equation:4s = 2s - 8Subtract 2s from each side:2s = -8Divide each side by 2 :s = -4
2s + 16 = 4s - 6 Subtract 2s from both sides: 16 = 2s - 6 Add 6 to both sides: 22 = 2s divide both sides by 2: s = 11
The simplified expression is 40 - 12s
16s + 4s = 20s
(4s + 1)(4s + 1) or (4s + 1)2
There is no answer since 4s - 2v8 cannot be simplified nor can it be evaluated without knowing the values of s and v.
It can't be factored because the discriminant of the given quadratic expression is less than zero

9s - 9
4s^2 + s - 14 = (4s - 7)(s + 2)

2s - 12 + 2s = 4s - 124s - 12 = 4s - 124s = 4ss = s==========this is an identity and any number can be s
