Question

Define quadratic equation and quadratic expression.

Answer 1

quadratic equation= any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power solve for x in the quadratic equation x2 + 4x + 4 = 0.

quadratic sequence=A quadratic expression is an expression involving a squared term, e.g., x2 + 1, or a product term, e.g., 3xy − 2x + 1. A linear expression such as x +1 is obviously non-quadratic. Always simplify the quadratic expression, if possible.

Explanation:

Answer 2

a quadratic equation is any equation that can be rearranged in standard form as ax^{2}+bx+c=0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no ax^2 term

An expression of the form ax2+bx+c a x 2 + b x + c , where a≠0 a ≠ 0 is called a quadratic expression
