Simplify the following expression:
\sqrt{A} + \sqrt{B}
First, try to factor any perfect squares out of the radicals.
= \sqrt{A} + \sqrt{B}
= \sqrt{pow( A_COEFF, 2 ) \cdot NUM} + \sqrt{pow( B_COEFF, 2 ) \cdot NUM}
Separate the radicals and simplify.
= \sqrt{pow( A_COEFF, 2 )} \cdot \sqrt{NUM} + \sqrt{pow( B_COEFF, 2 )} \cdot \sqrt{NUM}
= A_COEFF\sqrt{NUM} + B_COEFF\sqrt{NUM}
Finally, simplify by combining the terms.
= ( A_COEFF + B_COEFF )\sqrt{NUM} = A_COEFF + B_COEFF\sqrt{NUM}
Simplify the following expression:
\sqrt{A} - \sqrt{B}
First, try to factor any perfect squares out of the radicals.
= \sqrt{A} - \sqrt{B}
= \sqrt{pow( A_COEFF, 2 ) \cdot NUM} - \sqrt{pow( B_COEFF, 2 ) \cdot NUM}
Separate the radicals and simplify.
= \sqrt{pow( A_COEFF, 2 )} \cdot \sqrt{NUM} - \sqrt{pow( B_COEFF, 2 )} \cdot \sqrt{NUM}
= A_COEFF\sqrt{NUM} - B_COEFF\sqrt{NUM}
Finally, simplify by combining the terms.
= ( A_COEFF - B_COEFF )\sqrt{NUM} = A_COEFF - B_COEFF\sqrt{NUM}
Simplify the following expression:
\sqrt{A}B_SIGN\sqrt{B}C_SIGN\sqrt{C}
First, try to factor any perfect squares out of the radicals.
= \sqrt{A}B_SIGN\sqrt{B}C_SIGN\sqrt{C}
= \sqrt{pow( A_COEFF, 2 ) \cdot NUM}B_SIGN\sqrt{pow( B_COEFF, 2 ) \cdot NUM}C_SIGN\sqrt{pow( C_COEFF, 2 ) \cdot NUM}
Separate the radicals and simplify.
= \sqrt{pow( A_COEFF, 2 )} \cdot \sqrt{NUM}B_SIGN\sqrt{pow( B_COEFF, 2 )} \cdot \sqrt{NUM}C_SIGN\sqrt{pow( C_COEFF, 2 )} \cdot \sqrt{NUM}
= A_COEFF\sqrt{NUM}B_SIGNabs( B_COEFF )\sqrt{NUM}C_SIGNabs( C_COEFF )\sqrt{NUM}
Finally, simplify by combining the terms.
= ( A_COEFF + B_COEFF + C_COEFF )\sqrt{NUM} = A_COEFF + B_COEFF + C_COEFF\sqrt{NUM} = 0
