Question

x²-7x+6=0 को हल कीजिए।​

Answer 1

Answer:

${x}^{2} - 7x + 6 = 0 \\ {x}^{2} - 6x - x + 6 = 0 \\ x(x - 6) - (x - 6) = 0 \\ (x - 6) (x - 1) = 0 \\ x = 6 \: and \: 1$

hope it helps you.....Plzzzz mark me as brainlist

Answer 2

Step-by-step explanation:

x²-7x+6=0

compare equation with ax²+bx+c=0

a=1,b=-7,c=6

b²-4ac=(-7)²-4×1×6

=49-24

=25

by using formula,

x=-b+or-√b²-4ac

2a

x=-(-7)+or-√25

2x1

x=7+or-(-5 )

2

x=7+(-5) or x=7-(-5)

2. 2

x= 2 or x=7+5

2 2

x=1 or x=12

2

x=1 or x=6

the roots of equation is 1 and 6.
