Question

In the formula a^2 + b^2 = c^2 , what is the value of a^2 ?

A. c^2 – b^2
B. c^2 + b^2
C. b^2 + c^2
D. b^2 – c^2
The symbol ^ indicates the number after it is an exponent.

Answer 1

a^2 + b^2 = c^2 ; value of a^2?

Subtract b^2 to both sides

a^2 + b^2 - b^2 = c^2 - b^2

Simplify

a^2 = c^2 - b^2

Answer is A. c^2 – b^2

Answer 2

The answer would be A. c^2 – b^2
