Question 830149
x = (3/4 - 4t) to the power of 2. Rearrange to make t the subject of the equation. (to be read as x = (3 over 4 (fraction) - 4t) t the power of 2.

Please help.<pre>{{{x = (3/4 - 4t)^2}}}
{{{sqrt(x) = sqrt((3/4 - 4t)^2)}}} ----- Applying square root to both sides
{{{0 +- sqrt(x) = 3/4 - 4t}}}
{{{0 +- 4sqrt(x) = 3 - 16t}}} ------- Multiplying by LCD, 4
{{{- 3 +- 4sqrt(x) = - 16t}}}
{{{highlight_green((3 + 4sqrt(x))/16) = t}}}, or {{{highlight_green((- 3 - 4sqrt(x))/- 16) = t}}} 
You can do the check!!
