Determine, with explanation, whether each equation is quadric or not.
x + 1.5x² +9x⁴ = 0
No, the given has 4 as the highest exponent which is a quartic equation therefore not an example of quadratic equation.
8x + 2 + 5x² =4
Yes, the equation has 2 as the highest exponent which make it a quadratic equation.
4x² + 13x - 4x² = 3
No, the quadratic term will be cancelled which make it a linear equation.
