Answer» By definition the conjugate of XXX ( a + b ) is ( a − b )
and XXX ( a − b ) is ( a + b )
The term "conjugate" only applies to the sum or DIFFERENCE of TWO terms. "3 minus the square root of 2" MEANS (in algebraic form) 3 − √ 2
APPLYING the earlier definition with a = 3 and b = √ 2
we have The conjugate of ( 3 − √ 2 ) is ( 3 + √ 2 ) |
