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

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.
