What are quadratic in math?

  • A quadratic in mathematics is a particular kind of problem that involves squaring, or multiplying a variable by itself.
  • This terminology comes from the fact that a square's area equals the product of its side length and itself. Quadratum, the Latin word meaning square, is where the word "quadratic" originates.

Use the quadratic formula to find the solutions

x = - b + √b² - 4ac / 2a

Substitute the values

a = 1, b = 0, and c = − 9 into the quadratic formula and solve for x.

x = 0  +  √ 0² - 4 . ( 1 . 9 ) / 2. 1

Simplify

    The final answer is the combination of both solutions.

          x = 3,− 3
