Answer:
A
Step-by-step explanation:
Given the zeros are x = - 1 and x = 3 then the factors are
(x + 1) and (x - 3) and the parabola is the product of the factors, that is
y = a(x + 1)(x - 3) ← where a is a multiplier
To find a substitute (0, - 9) into the equation
- 9 = a(0 + 1)(0 - 3) = a(1)(- 3) = - 3a ( divide both sides by - 3 )
3 = a, thus
y = 3(x + 1)(x - 3) ← expand the factors using FOIL
= 3(x² - 2x - 3) ← distribute by 3
= 3x² - 6x - 9 → A
Prime factor is a factor that is a prime number.
Prime factors of :
8 : 2 × 2 × 2. Also can be written as

12 : 2 × 2 × 3. Also can be written as

20 : 2 × 2 × 5. Also can be written as

30 : 2 × 3 × 5
56 : 2 × 2 × 2 ×7. Also can be written as

70 : 2 × 5 × 7
You can find all of them by using Factor Tree [ as shown in the picture] or Dividing by prime numbers.

Step-by-step explanation:
Your question isn't really clear but let me help.
For Maths test,
Point earned = 30
Total point = 43
Percentage = 30/43 × 100 = 69.77%
Social studies test
Point earned = 85.
Total point = 124
Percentage = 85/124 × 100 = 68.55%
From the above, we can see that Jake scored a higher percentage in the Maths test.
None of them will get into a negative number. When you have like "2x" is the number twice, right? Some number has to be negative
Answer:
(25x2 + 4y2) (5x + 2y) (−5x + 2y)
Step-by-step explanation:
Factor 16y4−625x4
−625x4 + 16y4
=(25x2 + 4y2) (5x + 2y) (−5x + 2y)
