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

Lapatulllka [165]

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 $3x^2-4x+15$
