First we subtract eight from both sides of this equation and it becomes x squared minus four. X minus eight equals zero. Next we can identify the coefficients of this equation a close one vehicles minus four and Sequels minor thing. Then we substance, we substitute A B and say with their values. Into this formula, the dynamometer is to the numerator is four times plus of minors, the square root of minus four squared minus four times one times minus eight, which is four plus of minors square rollout 48/2 vehicles two plus, um, miners two times the square root house. Right? And if we use a calculator, their approximate value yes minus one point 464 and 5.46
