Common Mistakes to Avoid

✗ x3 + 5 ✓ 3x + 5 Numbers go before letters

✗ xx ✓ x² Use powers for repeated multiplication

✗ 1x ✓ x We don't write the coefficient 1

✗ 3 × x ✓ 3x No multiplication sign needed

✗ Confusing x² and 2x ✓ x² = x×x, but 2x = 2×x These are VERY different!

✗ Forgetting the sign: term is "7" ✓ In 3x − 7, constant is −7 The sign belongs to the term
