An Interesting Rational Equation Challenge: Can You Crack It?

X=-5,-7 .....thanks for sharing

10:04 45-7=38, so the expression factors to (7t^2+45)(t^2-1)=0 and you can skip the quadratic formula.

Let x+6 = t. It is clear that x is not equal to -6. Then, the equation reduces to 7t^4 + 38t^2-45 = 0. But t^2 is positive. So, t^2 = 1 > x = -5,-7.

x+6=t
