4(3x + 5)
= 4 × 3x + 4 × 5
= 12x + 20
2(x - 4) + 3(x + 5)
= 2x – 8 + 3x + 15
= 5x + 7
(x + 4)(x + 6)
= x (x + 6) + 4(x + 6)
= x² + 6x + 4x + 24
= x² + 10x + 24

anything outside the bracket has to be multiplied with each term inside it individually, its called expansion.
4(3x + 5) > 4 x 3x + 4 x 5 grouping them together gives 12x + 20
