Write in Standard Form (12x-1+2x^2)+(x^2+4)

$(12 x - 1 + 2 x^{2}) + (x^{2} + 4)$

Step 1

To write a polynomial in standard form, simplify and then arrange the terms in descending order.

$a x^{2} + b x + c$

Step 2

Add $- 1$ and $4$ .

$12 x + 2 x^{2} + x^{2} + 3$

Step 3

Add $2 x^{2}$ and $x^{2}$ .

$12 x + 3 x^{2} + 3$

Step 4

Reorder $12 x$ and $3 x^{2}$ .

$3 x^{2} + 12 x + 3$
