Step-by-step explanation:
A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable. One absolute rule is that the first constant "a" cannot be a zero.
<h3>Examples of quadratic equations include all of these:</h3>For this case we have the following expression:
We must rewrite it quadratically:
By definition, a quadratic equation is of the form:
Now, suppose
Rewriting the given expression with the change of variable we have:
So, we have a quadratic expression.
Returning the change we have:
