Given the expression: 3x^10 − 48x^2

photoshop1234 [79]

Answer:

Part A: 3x²(x⁸ - 16)

Part B: 3x²(x² - 2)(x² + 2) (x² - 2x + 2)(x² + 2x + 2)

Step-by-step explanation:

Part A. Factor out the greatest common factor

3x¹⁰ - 48 x²

= 3x²(x⁸ - 16)

Part B. Factor the expression completely

(i) Factor the difference of squares

x⁸ - 16

= (x⁴ - 4)(x⁴ + 4)

= (x² - 2)(x² + 2)(x⁴ + 4)

3x¹⁰ - 48 x² = 3x²(x² - 2)(x² + 2)(x⁴ + 4)

(ii) Factor the sum of squares

Use the Sophie Germain Identity to factor x⁴ + 4.

x⁴ + 4

= (x²)² + 2² (Still a sum of squares)

= (x² + 2)² - 4x² (Factor this as a difference of squares)

= (x² + 2 - 2x)(x² + 2 + 2x)

3x¹⁰ - 48 x² = 3x² (x² - 2)(x² + 2) (x² - 2x + 2)(x² + 2x + 2)

Can someone please put 1 1/4 cups 0.4 L 950 mL and 0.7 gallons in greatest to least

Yuliya22 [10]

Answer:

0.7 gallons, 950 mL, 0.4 L, 1 1/4 cups

Step-by-step explanation:

First we need to convert the information given into one unit, in this case I will convert it into liters (L)

CUPS

1 cup is equal to 236.588 ml and is the same as .236 L using this information and knowing that 1 1/4 cup is the same as 1.25 cups we have that

$x=\frac{1.25\times .236}{1}$

x=.295 L

LITERS

0.4 L will stay the same

MILILITERS

1 liter is 1000 ml so 950 ml is the same as

$x=\frac{950 \times 1}{1000}$

x=.950 L

GALLONS

1 gallon is 3.78541 L so 0.7 gallons are

$x=\frac{0.7 \times 3.785}{1}$

x=2.649 L

arranging the data from greatest to least we have that 0.7 gallons, 950 mL, 0.4 L, 1 1/4 cups
