Question

x (x+1) +8 = (x+2) (2-2)​

Answer 1

x (x+1) +8 = (x+2) (2-2)

=x (x+1) +8 = (x+2) 0

=x (x+1) +8 = 0

= x^2 + x + 8 = 0

a=1, b= 1, c= 8

Using formula of Sridhar Acharya,

x = -b +- root ( b^2 - 4ac)

2a

x = - 1 +- root ( 1 - 32)

2

x= - 1 +- root(-31)

2

x = - 1 + root(-31) , - 1 - root(-31)

2 2

Answer 2

Answer:

x² + x +8 = (X+2) (2-2)d

Step-by-step explanation:

x²+X+8= 2x -2x +4 -4

x² + x +8 = 0

(x+ 2√2)² + x = 0

x+ 2√2 + x = 0²

2x+2√2=0

2x = 2√2

x = 2√2/2

x= √2
