NikAS [45]

<u>5x² + 9x - 1</u><u> is  the expression that represents a </u><u>quadratic expression</u><u>.</u>

What is  quadratic expression?

  • Quadratic expression is an expression with the variable with the highest power of 2.
  • The word quadratic is derived from the word quad which means square.
  • The expression should have the power of two and not higher or lower.

A quadratic expression is of the form

ax² + bx +c = 0                    where a ≠ 0

The give options are-

9x - 2

5x² + 9x - 1

-2x³ + 8x² - 7x +1

x^{4} - 12 x^{3} + 8x^{2} - 7x +1

From the given options, the only expression which is quadratic is

5x² + 9x - 1

wChoose the expression that represents a quadratic expression. 9x − 2 5x2 9x − 1 −2x3 8x2 − 7x 1 x4 − 12x3 8x2 −here a =5, b=9 and c=-1

Therefore, 5x² + 9x - 1 is  the expression that represents a quadratic expression.
