If x = −b+√b2−4ac2a, then express the given formula in terms of a.
x(-c/x – 4b)
(c/x – 4b)/x
(-c/x – 4bx)/x
- ( c + xb )/x2
x = −b+√b2−4ac2a
(2ax+b)=√b2−4ac
(2ax+b)2=(b2−4ac) (Squaring both sides)
4a2x2+b2+4axb=b2−4ac
4a2x2+4axb=−4ac
ax2+xb=−c
a = −c−bxx2
x = −b+√b2−4ac2a, then express the given formula in terms of b.
If b2 – 4ac = 0 then The roots of the Quadratic equation ax2 + bx + c = 0 are given by :
