What is a quadratic equation?

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Express; 2x^{2} +5x-1 as a(x+b)^{2}+c

We have been given

a = 2 , b= 5 and c = -1.

Now, substitute the values;

$a(x+b)^{2}+c\\\\2(x+5)^{2}- 1$

Hence, the expression will be 2(x+5)^{2}- 1.
