Question

combine any like terms in the expression. if there are no like terms, rewrite the expression.
$32k^{2}+25k^{2}-18k^{2}-18k^{2}$

Explanation:

Step1: Group like terms

$(32k^2 + 25k^2) - (18k^2 + 18k^2)$

Step2: Calculate sums of coefficients

$(32+25)k^2 - (18+18)k^2 = 57k^2 - 36k^2$

Step3: Subtract remaining terms

$(57-36)k^2 = 21k^2$

Answer:

$21k^2$
