Question

what are two types of quadratic equations

Answer 1

One is the quadratic equation whose roots are real
and the second is quadratic equation whose roots are imaginary

Answer 2

There are not two but three types of quadratic equations. Standard Form, Factored Form, and Vertex Form.

• In algebra, a quadratic equation (from Latin quadratus 'square') is any equation that can be rearranged in standard form as $ax^{2} + bx + c = 0$
• The values of x that satisfy the equation are called solutions of the equation.
• A quadratic equation has at most two solutions.
• The Standard Form of a quadratic equation is $y = a x 2 + b x + c y=ax^2+bx+c y=ax2+bx+c.$
• The Factored Form of a quadratic equation is $y = a ( x - r 1 ) ( x - r 2 ) y=a(x-r_1)(x-r_2) y=a(x-r1)(x-r2)$
• The Vertex Form of a quadratic equation is $y = a ( x - h ) 2 + k y=a(x-h)^2+k y=a(x-h)2+k.$
• Hence, the three types of quadratic equations are the Standard Form, Factored Form, and Vertex Form.
