Question

Multiply and simplify: (9x + 5)(4x – 3)

A. 36x^2 – 47x – 15
B. 36x^2 –7x + 15
C. 36x^2 – 7x –15
D. 36x^2 – 47x + 15

Answer 1

\( \color{Black}{\Rightarrow (9x + 5)(4x - 3)}\)

\( \color{Black}{\Rightarrow 9x(4x - 3) + 5(4x - 3)}\)

Distribute and solve

Answer 2

\( \color{Black}{\Rightarrow 36x^2 - 27x + 20x - 15}\)

Continue from this point.

Answer 3

C ?

Answer 4

Yep

Answer 5

= 9x(4x - 3) +5(4x - 3)

Distribute as you did earlier and get the answer...
