What is the conjugate of the fraction

-10 +

Step-by-step explanation:

the importance of the conjugate is, when multiplied by the numerator and denominator, to remove the radical

for example, if you multiply (-10 - ) by (-10 + ) by using the foil method you get:

100 - 10 + 10 - 17

the two middle terms drop out and you are left with 83 in the denominator

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
