Factorising an equation is putting it into bracket form.
This has square numbers and so needs double brackets
(5x - y) (5x+y)
If you then check this by multiplying the brackets out again you will get:
5x^2 - 5xy + 5xy - y^2
The positive and negative 5xy's cancel each other out and you are left with its original form. Your answer is
(<span>5x - y) (5x+y)</span>
This is the concept of algebra, given a polynomial with one variable like x and y, the degree is the largest exponent of the variable;
Given the expressions;
4x^3-2y^3+5y^2-5y The polynomial has a degree of 3 (both y and x have an exponent of 3)
3y3--xy=3y^3+xy The polynomial has a degree of 3 also (y has an exponent of 3)
Answer:
7488 ft^3
Step-by-step explanation:
26x32x9 = 7488 cubic ft
1. The slope is -2/5 not 3-/10
