Can someone help me solve these problems? Thank you.


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


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

  1. Quidditch

    [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.
