Answer: a. x=0
b. h(-3)=5
Step-by-step explanation:
a. h(x)=-1
h(0)=-1
x=0
b. h(-3)=5
Factoring is decomposing a higher powered expression into a lower powered expressions that are multiplied together. Since (a-b)(a^2+ab+b^2) is lower powered than a^3-b^3, (a-b)(a^2+ab+b^2) is more simplified.
The Difference of Cubes formula shows up frequently in mathematics courses and should be memorized.
The formula for factoring the difference of cubes is (a^3 - b^3)= (a-b)(a^2+ab+b^2). It works because if (a-b)(a^2+ab+b^2) is multiplied it out, then it becomes a^3 - b^3. This was probably originally determined by trial and error a long time ago.
Since x is cubed and 8 is 2^3 it factors with the Difference of Cubes Formula. (x^3-2^3)=(x-2)(x^2+2x+2^2)=(x^2+2x+4)

Answer:i think b
Step-by-step explanation:
Answer:
n = 27
Step-by-step explanation:
Multiply both sides of the equation by 3
3 x 1/3n = 3 x 9
Reduce the number with the Greatest common factor (gcf) 3
n = 3 x 9
Multiply the numbers
n = 27
