Question

quadratic equation formulas​

Answer 1

:∆=b²-4ac

:x=-b±√(b²-4ac)/2a

to obtain Q.E having given roots

x²-(a+b)x+ab=0

(here a=alpha and b=beta)

Answer 2

Answer:

The quadratic formula helps us solve any quadratic equation first, we bring the equation to the form ax2+bx+c=0, where a, B, and c are coefficients. Then, we plug these coefficients in the formula (b+√(b२-4ac) /(2a)
