Can someone help me solve these problems? Thank you.

[SQRT(2x2 + 5x + 6)]=x

. [SQRT(x + 3)] = 2[SQRT(x)]

[SQRT(2x^2 + 5x +6) = x
square both sides
2x^2 + 5x + 6 = x^2
subtracting x^2 from both sides...
x^2 + 5x + 6 = 0
Factor by inspection or use the binomial theorem to solve for x.

The second problem is similar.
