Answer:
1.1 Factoring: x2-44
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 44 is not a square !!
Step-by-step explanation:
Answer: 0.49375, or 0.5
Step-by-step explanation: add up 2.34, -0.29, -0.45, and 0.38, which equals 1.975, then divide that by four (since there are 4 numbers) and you get 0.49375
