Imagine carbon is a master builder with multiple “hands” that can each hold onto another atom. Using these hands, carbon can build chains, rings, and complex structures that other elements can’t. Why is carbon’s ability to form so many bonds so important for life?

Solve the equation for x. Show every step on your paper. This question will require the quadratic formula. The quadratic formula is \( x= \frac{-b \pm \sqrt[]{b^2-4ac} }{2a} \). \( \frac{2}{x+2} – \frac{1}{x-1} =4 \) Once you solve for x and simplify your solutions, what is the numerical value that goes under the radical?
