Answer:
(a + 2b)(a - b)
Step-by-step explanation:
Assuming you require the expression to be factored
Given
a² + ab - b² ← factor out from each term
= (a² + ab - 2b²) ← factor the quadratic
Consider the factors of the coefficient of the b² term(- 2) which sum to give the coefficient of the ab- term (+ 1)
The factors are + 2 and - 1, since
2 × - 1 = - 2 and 2 - 1 = + 1, thus
a² + ab - 2b² = (a + 2b)(a - b) and
a² + ab - b² = (a + 2b)(a - b)
1. i think 5 to 9
2. i think 3/8

Answer:
4455
Step-by-step explanation:
135 pages x 33 lines a page = 4455 lines.
C rational numbers
natural numbers are numbers like
1, 2, 3, 4 etc
whole numbers are numbers without a fraction or decimals (natural)
irrational is just bunch of random numbers
7x-4=2
add 4 to both sides
7x=2+4
7x=6
divide 7 to both sides
x=6/7
