# The Number of Real Roots of The Equation x² – 3 lxl+2=0 is

**Answer: (1) 4 **

**Explanation:-
**X

^{2}– 3X + 2 = 0 and X

^{2}+ 3X + 2 = 0

For X

^{2}– 3 X + 2 = 0

D = (-3)

^{2}– 4 (2)(1) = 9 – 8 = 1 > 0

Therefore, X

^{2}+ 3X + 2 = 0 has two real

For X

^{2}+ 3 X + 2 = 0

D = (3)^2 – 4(2) (1) = 9 – 8 = 1 > 0

So, X

^{2}+ 3 lXl + 2 = 0

Then, the real roots is 4.

Hence, the answer is (1) 4.
