Polynomial Equations of Degree One
Equations in which the exponent of the variable is always one and the variable never appears as a divisor or under a radical sign are called
Subject: divisor
Transcript: NARRATOR: WE'VE BEEN CONCENTRATING ON EQUATIONS IN WHICH THE EXPONENT OF THE VARIABLE IS ALWAYS 1 AND THE VARIABLE NEVER APPEARS AS A DIVISOR OR
Additive and Multiplicative Inverses
Every number except zero has a multiplicative inverse. An explanation of multiplicative inverses and their usefulness in solving algebraic equations.
Subject: divisor
Transcript: 1. WE CAN DIVIDE A NUMBER BY ANOTHER NUMBER, OR WE CAN MULTIPLY THAT NUMBER BY THE DIVISOR'S MULTIPLICATIVE INVERSE. WE'LL GET THE SAME RESULT EITHER
Dividing Rational Expressions: Two Practice Problems
Practice problems for dividing rational expressions.
Subject: divisor
Transcript: STEPS WE'VE BEEN USING. WE'LL START BY WRITING THIS AS A MULTIPLICATION PROBLEM. WE'LL WRITE THE RECIPROCAL OF THE DIVISOR AND MULTIPLY IT BY THE DIVIDEND
Dividing Rational Expressions
The procedure for dividing rational expressions is demonstrated.
Subject: divisor
Transcript: NUMBERS. HERE'S AN EXAMPLE. TO SOLVE THIS DIVISION PROBLEM, WE MULTIPLY THE DIVIDEND BY THE RECIPROCAL OF THE DIVISOR. THE RECIPROCAL OF 15/2 IS 2/15. SO WE
