Question

Solve

a + 1=√b+1 for b

A. b = a^2 + 2a

B. b = a + 2a^2

C. b = 2a^2 + a

Answer 1

the first one shall be:

Answer 2

the rest are already solved for B.

Answer 3

do you know where i can find a calculater for these types of equations

Answer 4

To observe their graphs?

Answer 5

so the answer is b

Answer 6

am i right?

Answer 7

no. it is only a^2. because when you transport the one on the right to the left it will add with the other 1 and will give 0. squaring both sides makes a^2 and on the other side, b, thus a^2=b

Answer 8

b = a^2 + 2a?
