When 3x2 – 2x + 1 is subtracted from 2x2 + 7x + 5, the result will be what?

do I subtract 3x2 – 2x + 1 - 2x2 + 7x + 5 like this or 2x2 + 7x + 5 - 3x2 – 2x + 1 like this?

I would use the first way and then subtract ur like terms and simplify, if u want u can give it a try and I can check your work

I think you meant:

When 3x^2 – 2x + 1 is subtracted from 2x^2 + 7x + 5, the result will be what?

so 2x^2 + 7x + 5 - (3x^2 - 2x + 1)
= 2x^2 + 7x + 5 - 3x^2 + 2x - 1
= -x^2 + 9x + 4

all wrong

To subtract one polynomial from another, you need to pay attention to the order of the terms. The order of the terms matters because subtraction is not commutative, meaning changing the order of the terms will affect the result.

In this case, you want to subtract the polynomial 3x^2 – 2x + 1 from the polynomial 2x^2 + 7x + 5. The correct order of subtraction is:

2x^2 + 7x + 5 - (3x^2 – 2x + 1)

So, the correct way to subtract is to first distribute the negative sign to all the terms inside the parentheses:

2x^2 + 7x + 5 - 3x^2 + 2x - 1

Now, combine like terms by adding or subtracting the coefficients of the same degree variables:

(2x^2 - 3x^2) + (7x + 2x) + (5 - 1)

Simplifying further:

-x^2 + 9x + 4

Therefore, the result of subtracting 3x^2 – 2x + 1 from 2x^2 + 7x + 5 is -x^2 + 9x + 4.

First simplify! 3*2 - 2x + 1 = -2x + 7 and 2*2 + 7x + 5 = 7x + 9

NOW, you have the equation (7x + 9) - (7 - 2x) because the first is subtracted FROM the second in the original question. to solve, DISTRIBUTE YOUR NEGATIVE SIGN! It will become 7x + 9 - 7 + 2x because a negative times a negative makes a positive. Then, combine like terms. So, 7x + 2x becomes 9x
and 9 -7 becomes 2. This gives you the final answer, 9x + 2
