Answer:
A polynomial function that meet those conditions is x² + x - 2 = 0
Step-by-step explanation:
Hi there!
To solve this problem, let´s start writting a generic polynomial function in factored form. Since the function has two zeros, the factored form will have 2 terms:
(x+a)(x+b) = 0
For this equation to be 0, (x+a) or (x+b) have to be zero:
Then:
x + a = 0 ⇒ x = -a
In the same way:
x + b = 0 ⇒ x = -b
Then, the values "a" and "b" are equal to the zeros of the function but with the opposite sign.
In our case:
(x + a)(x + b) = 0
a = the zero of the function with opposite sign, that is, 2
b = -1
Then:
(x + 2)(x - 1) = 0
Apply distributive property:
x² - x + 2x - 2 = 0
x² + x - 2 = 0
Then, a polynomial function that meet those conditions is:
x² + x - 2 = 0

Answer:
The cost at both Laser Flash and Laser storm would be the same after 4 games
Step-by-step explanation:
Let the number of games be represented as x
Laser flash charges an initial fee of $16 for gear and $4 per game
For Laser flash , the Equation is:
$16 + $4 × x
y= 16 + 4x
Laser storm charges an initial fee of $20 for gear and $3 per game
$20 + $3 × x
y = 20 + 3x
Hence: Equating both costs to each other
Laser flash = Laser Storm
16 + 4x = 20 + 3x
Collect like terms
4x - 3x = 20 - 16
x = 4 games
The cost at both Laser Flash and Laser storm would be the same after 4 games
Keep, change, flip
Example: 3/4 divided by 6/8
Step 1: keep 3/4
Step two: change the division sign to a multiplication sign
Step 3: flip 6/8 and make it 8/6
Step 4: multiply it, then that’s your answer to the division problem
The numbers given in the question are 2/5, 4/9 and 3/7. We have to take them to decimal form for arranging the numbers in increasing order.
2/5 = 0.40
4/9 = 0.44
3/7 = 0.43
Then, the increasing order of the numbers would be
2/5 < 3/7 < 4/9
I hope the answer has helped you.
