$= 43 k^{2} + 58 k$ $= 43k^2+58k$

Multiply out the brackets and then collect like terms.

$3 k (k - 2) + 8 k (8 + 5 k)$ $3k(k-2) + 8k(8 +5k)$

$= 3 k^{2} - 6 k + 64 k + 40 k^{2}$ $=3k^2 - 6k + 64k + 40k^2$

$= 43 k^{2} + 58 k$ $= 43k^2+58k$

How do you simplify 3k(k-2)+8k(8+5k)3k(k−2)+8k(8+5k)3k(k-2)+8k(8+5k)?
