Expand this
3(x + 4)
Step 1 — Multiply the outside by the FIRST term
Step 2 — Multiply the outside by the SECOND term
Step 3 — Write both terms out
Expanding means multiply the term outside the brackets by every term inside, one at a time, then write the results out with their signs. Type your answer like 6x + 15 or 2a - 8 — spaces don't matter.
