Question

All Formula of quadratic equation​

Answer 1

Answer:

The quadratic formula is a general formula used for solving the quadratic equation: x = − b ± b 2 − 4 a c 2 a . Note that: if x2 = k, where k ≥ 0, then or same as x = ± k , where ± means “plus or minus.”

Example:

${ax}^{2} + bx + c = 0 \\ \\ \sf \: here \: abc \: are \: known \: numbers \: \\ \sf \: where \: a \not = 0 \\ \\ \sf \: x \: is \: unknown$

Answer 2

Answer:

algebra, a quadratic equation is any equation that can be rearranged in standard form as ax^{2}+bx+c=0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no ax^2 term.
