Question

Find the LCM of 35z^2+175z and 7z^2+42z+35

Answer 1

Start by factoring the two.

Answer 2

i dont think thats right.

Answer 3

Rosee, did you factor them?

Answer 4

Yeah i got 35z(z+5)(z+1)

Answer 5

\begin{array}{ccc}(7\cdot 5)z(z+5) & \text{and} & 7(z+5)(z+1)\end{array}
Are the fully factored forms:
So the LCM will be \[(7\cdot 5)z(z+1)(z+5) = 35z(z+1)(z+5)\]

So yeah, that's right.
