There are two ways to solve this equation. In the first method, we can simplify the quadratic by observation into two linear equations multiplied together, giving us (2x + 1)(x + 1) = 0. We can then set e...

By the quadratic formula, where a = 3, b = 5, c = 2 x = -2/3 and x = -1

(7,0)

Firstly, take the second equation and make either x or y the subject, which means to make it either x equals or y equals. To make x the subject, we take y away from both sides giving x=8-y. Then, substitu...

Ok I see why you are asking yourself this since right now you are only expressing certain formulae in a different way. Let me first talk about something else before giving you this answer. When you were i...
