Practice problem
Is there a way to expand the following? (1+2)×(4−3)(1+2)\times(4-3)(1+2)×(4−3)
1×4−1×3+2×4+2×31\times4 -1\times 3 +2\times 4 +2\times31×4−1×3+2×4+2×3
1×4−1×3+2×4−2×31\times4 -1\times 3 +2\times 4 -2\times31×4−1×3+2×4−2×3
4×1+4×2−3×1−3×24\times 1 +4\times 2 - 3\times 1 -3\times 24×1+4×2−3×1−3×2
4×1+4×2−3×1+3×24\times 1 +4\times 2 - 3\times 1 +3\times 24×1+4×2−3×1+3×2
Type a concept, like “slope” or “photosynthesis”.
