RS Aggarwal Class 10 Solutions Quadratic Equations
(i) x2-x+3=0 is a quadratic polynomial.
∴ x2-x+3=0 is a quadratic equation.
(ii) 2x2+ [latex]\frac { 5 }{ 2 } [/latex]x-√3=0
⇒ 4x2+5x-2√3=0
Clearly is 4x2+5x-2√3=0 a quadratic polynomial.
∴ 2x2+ [latex]\frac { 5 }{ 2 } [/latex]x-√3=0 is a quadratic equation.
