Question

Find the product.x^3(x2 + 5x + 1)​

Answer 1

Answer:

The product is;

x^5+5 x^4+x^3

Explanation:

Find the product;

x^3(x2+5x+1)

Step 1: Open the bracket

To open the bracket, we need to multiple the term outsied the bracket (x^3) each of the terms inside the brackets; x2, 5x and 1

This can be done as follows;

(x3×x2)+(x3×5x)+(x3×1)

Step 2: Solve

Since the product of x3 and x2, have the same base x, it can be solved by maintaining the base x and getting the sum of the powers 3 and 2. This can be written as;

x^(3+2)=x^5

To solve the product of 5 x and x^3, we use the same concept as above as shown;

(5 x)×(x^3), adding the powers of x and x^3 as shown;

5 x^(1+3)=5 x^4

In solving the product of x^3 and 1 the answer will just be x^3 since any term multiplied by 1 equals the same term.

In that case;

x^3

Step 3: Put the results of the terms together

(x^5)+5 (x^4)+x^3

This can be further simplified to;

x^5+5 x^4+x^3
