Question

Check whether the following equations are quadratic or not ?
(i) x² − 6x − 4 = 0 (ii) x³ − 6x² + 2x − 1 = 0
(iii) 7x = 2x² (iv) x² + 1/x² = 2
(v) (2x + 1) (3x + 1) = b(x − 1) (x − 2) (vi) 3y² = 192

Answer 1

it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.
