Answer (2x + 7) • (x2 - 2)
Step-by-step explanation:
please give me brainlest!!
Step by step solution :
Step 1 :
Trying to factor as a Difference of Squares :
1.1 Factoring: x2-2
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 : 2 is not a square !!
Ruling : Binomial can not be factored as the difference of two perfect squares.
Final result :
(2x + 7) • (x2 - 2)
Answer:
x=2
Step-by-step explanation:
7x - 3 = 11
Add 3 to each side
7x - 3+3 = 11+3
7x = 14
Divide by 7
7x/7 = 14/7
x = 2
3.6 / 0.2 = 18 liter glasses :))
32 tens do equal 320 ones
Answer:
The three consecutive odd integers are: -1, 1, 3
Step-by-step explanation:
The three consecutive odd integers be x, x + 2, x + 4
Now according to the question
It is mentioned that
The four times the middle integer is two lower than tfhe sum of the first and third
i.e.
4(x+2) = [x + (x+4)] + 2
4x + 8 = 2x + 6
2x = -2
x = -1
Hence, The three consecutive odd integers are: -1, 1, 3
