1+4=5
The GCF is 24xy^2
(x7 - y7) = (x - y)(x6 + x5y + x4y2 + x3y3 + x2y4 + xy5 + y6)
What is a literal coefficient? Expressions are made up of terms joined by adding and subtracting. Terms are made up of numbers and variables multiplied together. In the term 3xy5, 3 is the (numerical) coefficient, and xy5 is the literal coefficient.
If you have like terms then to multiply you add the exponents and to divide you subtract.So, x2 * x3 = x5 and y7 / y5 = y2Also, for example, 2x2 * x3 = 2x5 (we can do this as the terms are like; x's only)But if you do not have like terms then this does not apply.For example, x2 * y3 does not equal xy5.
Excluding calculus (which is, in fact, a part of algebra), the degree of an expression is the maximum sum of the powers of the variables in the expression.Consider the expression x2y3 + xy5 + 17x4 The sums of the powers of the three terms are: 2+3 = 5, 1+5 = 6 and 4=4 So the expression is of degree 6.
