Question

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

Answer 1

Answer:

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

Step-by-step 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 $3x^2-4x+15$

Answer 2

Answer:

(5x^2+3)-(2x^2+4x-12) = 3x²-4x+15.

Step-by-step 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.
