Hi sir/mam i have a querry that if the quadratic equation can have maximum of only two roots. why is it said to be quadratic equation even when quadratic means having four roots. what's the reason behind it?

The name quadratic equation comes from the word, \'quad\'.
 
Quad means square, that is the variable getting squared - «math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«msup»«mi»x«/mi»«mn»2«/mn»«/msup»«/math»
Quadratic equation is an equation having two roots.
 
Therefore, quadratic equation means the equation containing the squared terms of the variable.
 
Quartic equation means, equation having terms of powers of 4 for the variable.
 
Quartic equation is also called as biquadratic equation.
 
And the roots of the biquadratic equation are four.

For a real number r, the quadratics x² + (r - 1) x + 6 and x² + (2r + 1) x + 22 have a common real root. The sum of the possible values of r can be expressed as a/ b where a, b are relatively prime positive integers. Compute 10a + b
