Luca solved an equation as shown , and verified that his solution was correct . sqrt(2x - 5) = sqrt(x - 3) + 1 1 (sqrt(2x - 5)) ^ 2 = (sqrt(x - 3) + 1) ^ 2 1 2x - 5 = x - 3 + 1 x = 3 Explain what Luca's error is and why his answer is not completely correct .

If x = -2, then x 2-7x+10 equals a. 0 b.20 c.28

Which expression is equal to (f+g)(x)?
