Explain step by step how to use the horizontal method the multiple the two polynomials
Answers
Answer:
Step-by-step explanation:
Multiply each term of the first polynomial with the second polynomial. Then combine the like terms.
(3a² + 5a - 2)* (5a² -3a + 4)
= 3a² *(5a² -3a + 4) + 5a*(5a² -3a + 4) - 2*(5a² -3a + 4)
=3a²*5a² - 3a*3a² + 4*3a² + 5a*5a² - 3a*5a + 4*5a + 5a²*(-2) - 3a*(-2) + 4*(-2)
=15a⁴ - 9a³ + 12a² + 25a³ - 15a² + 20a - 10a² + 6a - 8
= 15a⁴ - 9a³ + 25a³ + 12a² - 15a² - 10a² + 20a +6a - 8
= 15a⁴ + 16a³ - 13a² +26a - 8

Answers
Answer and Step-by-step explanation:
The independent variable is m, and the dependent variable is h.
This is because you can plug in any value for m, making m NOT have to depend on any other value to become m.
With h, it needs the result of m and its other values to become the result of h. H relies/depends on the values in the equation to become a value.

Given g(x)=-2x+2, solve for x when g(x)=8
Answers
Answer:
x=±3. Explanation: g(x)=2x2−10 g(x)=8. ie 2x2−10=8 2x2=18 x2=9 x=±3.
Step-by-step explanation:
To solve this, first set -2x + 2 = 8
Now you want to try to get x alone on one side so subtract 2 on both sides
-2x = 6
Finally divide both sides by -2 to find out what x is equal to
x =-3
To check if this is the right answer, plug -3 in for x in the original equation and see if it comes out as 8
-2(-3) + 2 = 8
6 + 2 = 8
8 = 8
Both sides are equal so -3 is the solution
