Question

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

Answer 1

Answer:

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

Step-by-step explanation:

Given expression is $(5x^2+3)-(2x^2+4x-12)$.

Now we need to subtract them.

We are allowed to 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:

(5x² + 3) - ( 2x² + 4x - 12) = 3x² - 4x + 15

Step-by-step explanation:

The given expression is

(5x² + 3) - ( 2x² + 4x - 12)

To find the subtraction result

(5x² + 3) - ( 2x² + 4x - 12) = 5x² + 3 - 2x² - 4x + 12

= 5x² - 2x² - 4x + 3 + 12

= 3x² - 4x + 15

Therefore the correct answer is

(5x² + 3) - ( 2x² + 4x - 12) = 3x² - 4x + 15
