Jack wants to simplify the expression below.

mamaluj [8]

Answer:

5.3x - 4 .

Step-by-step explanation:

(6.7x -3) - (3.4x - 1) + (2x - 2)

1. using the commutative property:

= 6.7x - 3 + 2x - 2 - (3.4x - 1) (we can remove the parentheses around the first 2 groups because they are added).

2. Using the distributive property on the last group:

= 6.7x - 3 + 2x - 2 - 3.4x + 1 (distributing the negative over the parentheses).

3. Now adding like terms we get:

5.3x - 4 (answer).

Which two values of x are roots of the polynomial below 5x^2-5x+1

damaskus [11]

To find roots of a polynomial, you have to find numbers that when you multiply will equal 5 (because 5*1) and add to -5. since the only factors of 5 are 1 & 5, they do not equal -5. you will have to use the quadratic formula to find the roots. if you want decimals, they are 0.723607 & 0.276393
