Question

x and B are the zeroes of x*x -3x+2 then find the value of x*x +b*b​

Answer 1

Answer:

5

Step-by-step explanation:

since x and b are zeroes

=> x+b= -(-3)/1=3

and xb= 2/1=2 ......... [1]

$sum \: of \: zeroes = \frac{ - b }{a }$

and

$product \: of \: zeroes = \frac{c}{a}$

x+b=3

=> (x+b)²=9

=>x²+b²+2xb=9

=> x²+b²+4=9 ( xb=2 from above)

therefore

x²+b²=5
