Question

Solve for t by factoring
16(t^2-6t-36)=0
I think you should come up with at least two answers

Answer 1

\(\Large \color{purple}{\rightarrow t^2 - 6t - 36 }\)

Do the quadratic factoring.

Answer 2

That's what I tried to do, but none of the factors of -36 add up to -6

Answer 3

right - this needs to be solved by completing the square or by using the formula

Answer 4

\(\Large \color{purple}{\rightarrow 16[t(t - 6) - 36] }\)

Answer 5

ahh yes t(t -6 ) = 36

Answer 6

Yep :D

Answer 7

can you continue from here rav?

Answer 8

@campbell you can solve this by completing the square right? - or is there some other way (not by the formula)

Answer 9

use quadratic formula
