6t - 8 - 5t^2  + 2

-5t^2 + 6t - 6

by the sum of roots and product of roots formulae

ax^2 + bx + c

Please Hurry! What is the solution to log2_(9x)-log2_3=3?
brilliants [131]

Answer:

log_{2}(9x)  - log_{2}(3) = 3 \\ 3 =  log_{2}(8) or log_{2}( {2}^{3} )  \\  log_{2}( \frac{9x}{3} )  = log_{2}(8) \\  \frac{9x}{3}  = 8 \\ 9x = 8 \times 3 \\ 9x = 24 \\ x =  \frac{24}{9}  \\ x =  \frac{8}{3}  \\ x = 2 \times \frac{2}{3}
