Answer:
-2x³ + x² - 3x - 15
Step-by-step explanation:
Simply combine like terms together:
-5x² - 3x - 7 - 2x³ + 6x² - 8
-2x³ + (-5x² + 6x²) - 3x + (-7 - 8)
-2x³ + x² - 3x + (-7 - 8)
-2x³ + x² - 3x - 15
Answer:
this trinomial is prime, and cannot be factored.
Step-by-step explanation:
when expanding the equation, you multiply the last term by the first term's coefficient, and then find two factors that multiply to that product, and sum to the middle coefficient.
1 * 19 = 19
there are no factors that will multiply to 19 and sum to 11. thus, this polynomial is prime.
Answer:
x = 57/5 = 11.400
Step-by-step explanation:
Step 1 :
Solving a Single Variable Equation :
1.1 Solve : 5x-57 = 0
Add 57 to both sides of the equation :
5x = 57
Divide both sides of the equation by 5:
x = 57/5 = 11.400
One solution was found :
x = 57/5 = 11.400
