To find x = ?
when,
|x2+3x+5|+x2+3x+5=0−−−−−−−(1)|x2+3x+5|+x2+3x+5=0−−−−−−−(1)
Let, x2+3x+5=φx2+3x+5=φ
Now, (1)(1)becomes,
|φ|+φ=0|φ|+φ=0
We know that,
|φ|=±φ|φ|=±φ
This means, we have two scenarios,
−φ+φ=0−−−−−−−−−−−−−−(2)−φ+φ=0−−−−−−−−−−−−−−(2)
and,
φ+φ=0−−−−−−−−−−−−−−−(3)φ+φ=0−−−−−−−−−−−−−−−(3)
Now,
Equation (2) gives, φ=φφ=φ
This is rather insignificant.
Equation (3) gives, 2φ=02φ=0
⟹φ=0———————————−(4)⟹φ=0———————————−(4)
Thus,
x2+3x+5=0x2+3x+5=0from(4)
Now, using the Quadratic Formula,
x=−b±b2−4ac√2ax=−b±b2−4ac2a
Here, a = 1, b = 3 and c = 5,
substituting the values we will get −3±i11√2
Hope it's help you
