Question

The sum of the roots of the equation x2 – 5x +3 = 2x + 11 is​

Answer 1

Answer:

after rearranging we get tbe polynomial as

x^2 - 5x + 3 - 2x - 11 = 0

x^2 - 7x - 8 = 0

a = 1, b= -7 and c= -8

sum of roots = -b/a

= -(-7)/1

= 7

Answer 2

2+5×+3=2×+11

5+5×=2×+11

5×-2×=11-5

3×=6

×=2
