Solution

The correct option is A

8,5


Given, x+5=2x+10x6

(x+5)(x6)=(2x+10)x23x40=0

For the standard form of quadratic equation ax2 + bx + c = 0, roots are b±b24ac2a.

Here, a=1,b=3 and c=40

Roots roots o the quadratic equation are:
x=(3)±324×1×(40)2×1 =3 ±9 + 1602 =3 ±1692 =3 ±132x=3 +132 or 3 132 =162 or 102 =8 or 5

Hence, roots of the equation x+5=2x+10x6 are 8,5
