Q. Simplify. Rationalize the denominator. −6−310
Find Conjugate: Select the conjugate of −6−3.Conjugate of a−b: a+bConjugate of −6−3: −6+3
Multiply by Conjugate: Multiply the numerator and the denominator by the conjugate of the denominator.To rationalize the denominator, we multiply the expression by (-6 + \sqrt{3})/(-6 + \sqrt{3})\(\newline\).(10/(−6−3))×((−6+3)/(−6+3))
Simplify Numerator: Simplify the numerator by distributing the multiplication.10×(−6+3)= 10×(−6)+10×(3)= −60+103
Simplify Denominator: Simplify the denominator using the difference of squares formula.(−6−3)∗(−6+3)= (−6)2−(3)2= 36−3= 33
Write Simplified Expression: Write the simplified expression. (−60+103)/33 This fraction is already in simplest form.
