Question

The expression
(11.98 11.98 +11.98*x+0.02 0.02)
will be a perfect square for x equal to
1) 0.02
2) 0.2
3) 0.0
4) 0.4​

Answer 1

Answer:

0.04

Step-by-step explanation:

it is in the form of

(a^2) +(2(a^b))+(b^b)

where [(a+b)^2 ] = [(a^2) +(2(a*b))+(b^b)]

let a =11.98

b = 0.02

so 11.98* x = 2(a*b)

11.98* x = 2((11.98)*(0.02))

hence x = 0.04
