(polynomials) multiply. (x^2-5x)(2x^2+x-3)
a. 2x^4 - 9x^3 - 9x^2 - 15x
b. 2x^4 + 9x^3 - 8x^2 + 15x
c. 4x^4 + 9x^3 - 8x^2 + 15x
d. 2x^4 - 9x^3 - 8x^2 + 15x

2x^4 - 9x^3 -8x^2 + 15x

Step-by-step explanation:

(x^2-5x)(2x^2+x-3) distribute first

2x^4

x^2 + x = x^3

5 * 2x^2 x= 10x^3

5x^1+1 = 5x^2

5 * 3x = 15x Put them all together

2x^4 + x^3 - 3x^2 - 10x^3 - 5x^2 + 15x Like terms

2x^4 + x^3 -10x^3 - 3x^2- 5x^2 + 15x Add similar terms

= 2x^4 + x^3 - 10x^3 - 8x^2 + 15x more adding terms

2x^4 - 9x^3 -8x^2 + 15x

Hope my answer has helped you, if not i'm sorry.

For this case we must multiply the following expression:

We apply distributive property term to term taking into account that:

For powers of the same base, we place the same base and add the exponents:

We add similar terms:

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
