Answer:
5x²- 1.8
Step-by-step explanation:
roots are -3 and 3, put them in brackets
(x - 3)(x + 3)
x² + 3x - 3x - 9
x² - 9
5x = -9
x = -1.8
5x² - 1.8
just to check:
5x² - 1.8
x² - 9
(x - 3)(x - 3)
x = -3 and 3.
Answer:2/4 more joseph ate
Step-by-step explanation:
-- A negative exponent means the number is in the denominator.
b⁻³ means 1/b³ .
So 1/b³ = 1/216 . You can do it now.
-- If that number is " 10³ ", it means 1,000 .
If that number is " 103 " and you can't remember
how to do multiplication with a pencil, then you'll
have to use your calculator.
-- Again ... 10⁻³ means 1/10³ or 1/1000 .
So the problem is really 36 divided by 1/1000 .
Be very careful. That means 36 x 1000 .
-- To multiply powers that have the same base,
you add the exponents.
Example: 10⁴ times 10⁵ = 10⁹ .
This question can be rearranged as (2.1 x 4) x (10³ x 10⁻⁷)
(10³) times (10⁻⁷) is 10⁻⁴ .
