Question

find the roots of equation x²+5=6=0 by using formula.​

Answer 1

Answer: Using the quadratic formula, the roots of the equation x2 - 5x + 6 are 2 and 3.

Step-by-step explanation:

Comparing the equation with ax2+bx+c = 0 gives,

a = 1, b = -5 and c = 6

b2-4ac = (-5)2-4×1×6 = 1

Roots of the equations are

−b +√( b2 − 4ac) /2a

= 5 + 12 = 62

= 3

Another root

−b -√( b2 − 4ac) /2a

= 5 − 12

= 42

= 2
