What is 24t - 8t^2=-1? Please help?

Question

thank you

Answer 1

24t - 8t² = -1

First multiply thru by -1

8t² - 24t = 1

Now subtract 1 from both sides

8t² - 24t -1 = 0

I think the easiest way to solve for t is the quadratic formula.

ax² + bx + c = 0
x = (-b +- √(b² - 4ac))/2a

x= (24 +- √(576 + 32))/16

x= (24 +- √(16*38))/16

x= (24 +- 4√(38))/16

Divide numerator and denominator by 4

x= (6 +- √(38))/4

x = 3.0411, x = -0.0411
.

Answer 2

in view which you at the instant are not multiplying or dividing, you could overlook on the topic of the parenthesis. Now you combine your "like" words (those with t2, t and numbers without t) (3t - 3) + (6t2 + 4t + 13) + (-8t2 + 11t - a million) 6t2 - 8t2 = -2t2 3t + 4t + 11t = 18t -3 +13 -a million = 9 So your answer is: -2t2 +18 +9

Answer 3

Good Luck with that.
