5(t(squared)2)To be squared7(t(squarded)2)10=0

Hi djsutt0n! When you simplify one side of the equation, you get 5t^4  27^2 + 24 = 0. This ends up being a quartic equation, and unfortunately, this is not covered in the Junior Cert Maths course (for your interest, this is the answer: x = 2.0683262276067467 or x = 1.0592575778317774 or x = 1.0592575778317774 or x = 2.0683262276067467).
Doublecheck your equation and try and make sure you have it written correctly.

(Ignore my first post, I made a slight mistake.)

Thanks a lot but this came up in my mocks?

Are you sure 5(t^22) was to be squared?

Roberto Mane
Use the minus B formula to solve that question,you must've got the same mock as me...I remember that question.

Dazzla16
@Roberto Mane please call it the quadratic formula.

Also, @Roberto Mane do you know if 5(t^22) is to be squared? Can you rewrite the question (djsutt0n may do this instead) so that it is easier to understand. I don't know whether 5(t^22) is to be squared, or only (t^22) is to be squared. Use brackets if you need to.
