What is a quadratic equation?

The polynomial equation whose highest degree is two is called a quadratic equation. The equation denoted by ax² + bx + c = 0, where a is non-zero.

Let us calculate the roots by factorization

[tex]x^{2} -11x+3x-33=0[/tex]

[tex]x(x-11)+3(x-11)=0[/tex]

[tex](x-11) (x+3)=0[/tex]

[tex]x-11=0\\x=11\\x+3=0\\x=-3[/tex]

Hence, the solution set of the given quadratic equation will be {-3,11}
