10x^2-23x+13
(10x-13)(X-1). Answer
Look at steps to learn this try not to just copy answer
10x(X-1)= 10x^2-10x
-13(X-1)= -13x+13
-10x^2-10x-13x+13
-10x^2-23x+13
Answer:
Step-by-step explanation:
There would be 5184 ways in which each subject books can be selected.
<u>Explanation:</u>
Number of geography books = 5
Number of chemistry books = 4
Number of Science books = 7
Different ways of selecting geography books = 5!
= 5 X 4 X 3 X 2 X 1
= 120
Different ways of selecting chemistry books = 4!
= 4 X 3 X 2 X 1
= 24
Different ways of selecting Science books = 7!
= 7 X 6 X 5 X 4 X 3 X 2 X 1
= 5040
Total different possible ways they can select them = 120 + 24 + 5040
= 5184
Answer:
Step-by-step explanation:
16x⁸ - 81y⁸ is the difference of squares.
16x⁸ - 81y⁸ = (4x⁴)² - (9y⁴)² = (4x⁴ + 9y⁴)(4x⁴ - 9y⁴)
Note that 4x⁴ - 9y⁴ is also the difference of squares.
4x⁴ - 9y⁴ = (2x²) - (3y²)² = (2x² + 3y²)(2x² - 3y²)
16x⁸ - 81y⁸ = (4x⁴ + 9y⁴)(2x² + 3y²)(2x² - 3y²)
