Write in Standard Form (5x^2+8x)+(x^2-5x+1)

$(5 x^{2} + 8 x) + (x^{2} - 5 x + 1)$

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

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

Add $5 x^{2}$ and $x^{2}$ .

$6 x^{2} + 8 x - 5 x + 1$

Subtract $5 x$ from $8 x$ .

$6 x^{2} + 3 x + 1$
