Question

Subtract (5x^2+3)-(2x^2+4x-12)

Answer 1

(5x^2+3)-(2x^2+4x-12) = 3x²-4x+15.

Explanation:

We have given the expression:

(5x²+3)-(2x²+4x-12)

We have to subtract.

(5x²+3)-(2x²+4x-12)

5x²+3-2x²-4x+12

5x²-2x²-4x+3+12

3x²-4x+15

3x²-4x+15 is the answer.

Answer 2

Final answer is
`3x^2-4x+15`

Explanation:

we have been given an expression
`(5x^2+3)-(2x^2+4x-12)`.

Now we need to subtract them.

We can subtract like terms only that has same variable with same exponent.

`(5x^2+3)-(2x^2+4x-12)`

`=5x^2+3-2x^2-4x+12`

`=5x^2-2x^2-4x+3+12`

`=(5-2)x^2-4x+(3+12)`

`=(3)x^2-4x+(15)`

`=3x^2-4x+15`

Hence final answer is
`3x^2-4x+15`
