The discussion revolves around solving a quadratic equation using the formula method. The original poster presents the equation 3t^2 + 7t = 5 and attempts to solve it, expressing confusion over discrepancies between their results and those provided by a tutor's answer book.
The discussion is ongoing, with participants identifying possible mistakes in the original poster's calculations. There is a recognition of a specific error in the denominator, but no consensus has been reached regarding the correct approach or final answers.
Participants are working under the constraints of homework rules, which may limit the sharing of complete solutions. There is an emphasis on understanding the reasoning behind the calculations rather than simply providing answers.
In the denominator, 2(3) does not equal 4.lloydowen said:3t^2+7t-5=0<br /> t= \frac{-7 +or-\sqrt{7^2-4(3)(-5)}}{2(3)}<br /> <br /> t= \frac{-7+\sqrt{109}}{4}<br /> t= -4.39<br /> OR...
t= \frac{-7-\sqrt{109}}{4}<br /> t= -9.61
The reason I have doubts is because the answer book from the tutor shows, T= 0.573 or -2.907... ? :(
