First we can identify the confessions of this equation A equals two vehicles. Five vehicles. Next we substitute A B and C. With their values. Into this format, the numerator, yes minus five class on minors. The square root of five squared minus four times two times two, and the gentleman ator is two times. So this equals minus five plus minors. The square root out miners 55 or four. Here we need to use I, which is the unit of the imaginary number, and I echoes square road on minors one. So the first solution is minus five miners square road off 55 I over for. And the second solution is minus five plus the square root of 55 I over four.
