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
Oh, dude, 3x4t is just 12t. Like, you just multiply 3 and 4 to get 12, and then you tack on that "t" at the end because it's hanging out there, lonely and wanting to be part of the math party. So, yeah, 12t is the answer.
(t - 15)(t + 3)
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
