Given the expression: 3x10 - 48x2
Part A: Rewrite the expression by factoring out the greatest common factor. (4 points)
Part B: Factor the entire expression completely. Show the steps of your work. (6 points)

a.  3x^2 ( x^8 - 16 )

b.  3x^2 ( x^2     - 2 )  (x^2 +2)( x^4   +4 )

Step-by-step explanation:

3x^10 - 48x^2

We can factor out 3 x^2

3x^2 ( x^8 - 16 )

We know the terms inside the parentheses is the difference of squares and

(a^2 -b^2) = (a-b) (a+b)

3x^2 ( x^4 ^2   - 4^2 )

3x^2 ( x^4    - 4 )( x^4   +4 )

The first term in parentheses is the difference of squares

3x^2 ( x^2 ^2    - 2^2 )( x^4   +4 )

3x^2 ( x^2     - 2 )  (x^2 +2)( x^4   +4 )

A) 3x²(x⁸ - 16)

B) 3x²(x⁴ + 4)(x² - 2)(x² + 2)

Step-by-step explanation:

3x¹⁰ - 48x²

3x²(x⁸ - 16)

3x²[(x⁴)² - 4²]

3x²[(x⁴ - 4)(x⁴ + 4)]

3x²(x⁴ + 4)[(x²)² - 2²]

3x²(x⁴ + 4)(x² - 2)(x² + 2)

i understand 100% 10/10 hit or miss?

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
