Question
Multiply the binomials: $(2x + 5)$ and $(4x - 3)$.
✓
Answer
$(2x + 5 )$$\times$$(4x - 3)$
$= 2x(4x - 3) + 5(4x - 3)$
$= 2x \times 4x - 2x \times 3 + 5 \times 4x - 5 \times 3$
$= 8x^2- 6x + 20x - 15$
$= 8x^2+ 14x - 15$
$= 2x(4x - 3) + 5(4x - 3)$
$= 2x \times 4x - 2x \times 3 + 5 \times 4x - 5 \times 3$
$= 8x^2- 6x + 20x - 15$
$= 8x^2+ 14x - 15$
