So negative 10x is equal to 0. Divide both sides by negative 10, and you get x is equal to 0. And now we can substitute back into either of these equations to figure out what y must be equal to. Let's substitute into the top equation. So we get 5 times 0, minus 10y, is equal to 15. Or negative 10y is equal to 15. It is possible to solve equations with x^2 and y^2 terms by the same methods we have used so far. If x^2 or y^2 terms appear, try to collect them on one side of the equation. If the squared term drops out, you may solve it as a first-degree equation using the methods discussed in this section. EXAMPLE 5 Solve for y. 5y^2 + 6y -2 = -y + 5y^2 + 12
Dividing both sides by 𝑔' (𝑦) we get the separable differential equation. 𝑑𝑦∕𝑑𝑥 = 𝑓 ' (𝑥)∕𝑔' (𝑦) To conclude, a separable equation is basically nothing but the result of implicit differentiation, and to solve it we just reverse that process, namely take the antiderivative of both sides.

Use Algebra to solve: A "root" is when y is zero: 2x+1 = 0. Subtract 1 from both sides: 2x = −1. Divide both sides by 2: x = −1/2. And that is the solution: x = −1/2. (You can also see this on the graph) We can also solve Quadratic Polynomials using basic algebra (read that page for an explanation). 2.
Put the equation in standard form. x2 − 9 = 0. Factor the difference of squares. (x − 3)(x + 3) = 0. Use the Zero Produce Property. x − 3 = 0 x − 3 = 0. Solve each equation. x = 3 x = − 3. We can easily use factoring to find the solutions of similar equations, like x2 = 16 and x2 = 25, because 16 and 25 are perfect squares. Sts2fQD. 8692291481599725224329
