Divide all terms by -1:
5t2-12t-9 = 0
(5t+3)(3t-3) = 0
Therefore: t = -3/5 and t = 3
Use the quadratic equation formula.
If you mean: 9t^2 +12t +4 then it is (3t+2)(3t+2) when factored
The answer is 55 + 12t.
12(t+6)+8=4(2t-1)+2t 12t+72+8=8t-4+2t 12t-2t-8t=-72-8-4 2t=-84 2t/2=84/2 t=42
12t + 15
12 (t -6) + 8 4 (2t - 1)Distribute: 12t-72+8 8t-4Combine like terms: 12+-64 8tSubtract 12t from each side: -64 -4tMultiply each side by -1: 64 4tDivide each side by 4: 16 tSo t = 16
-12t+4
12t(t2-4) 12t(t-2)(t+2)
7s plus 8t plus 10s plus 12t can be simplified to 17s plus 20t.
If you mean: 9t^2 +12t +4 then it is (3t+2)(3t+2) when factored
6t
That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: (-7 plus or minus i times the square root of 23) divided by -3x = 2.3333333333333335 + -1.5986105077709063ix = 2.3333333333333335 - -1.5986105077709063iwhere i is the square root of negative 1
The answer is 55 + 12t.
12(t+6)+8=4(2t-1)+2t 12t+72+8=8t-4+2t 12t-2t-8t=-72-8-4 2t=-84 2t/2=84/2 t=42
The answer is 12t.
