Answer:
x(x - 7)(x^3 + 2)
Step-by-step explanation:
Note that x is a common factor here:
3x^5-7x^4+6x^2-14x = x(3x^4 - 7x^3 + 6x - 14), or:
x(3x^4 - 7x^3 + 6x - 14) Note that 6x - 14 can be rewritten as 2[x - 7]
and that 3x^4 - 7x^3 can be rewritten as x^3[x - 7]
Therefore, x(3x^4 - 7x^3 + 6x - 14 becomes:
x(x - 7)(x^3 + 2)
Answer:
When k(x) is 2x² - 5x + 3, k(-3) = 36.
Step-by-step explanation:
k(x) = 2x² - 5x + 3
Substitute the input of x.
k(-3) = 2(-3)² - 5(-3) + 3
Square -3.
k(-3) = 2(9) - 5(-3) + 3
Multiply 2 and 9.
k(-3) = 18 - 5(-3) + 3
Multiply -5 and -3.
k(-3) = 18 + 15 + 3
Add 18 and 15.
k(-3) = 33 + 3
Add 33 and 3.
k(-3) = 36.
He added incorrectly , meaning he would have to do 8 times 24
