Question

B (Find the product of (4X + 9) (X-6)​

Answer 1

Answer:

answer of the question is 4x²+9x-60

Answer 2

We have to find the product of (4x + 9)(x - 6)

This is in the form (a + b)(c - d).

$\boxed{\bf (a + b)(c - d) = ac - ad + bc - bd}$

Here,

• a = 4x

• b = 9

• c = x

• d = 6

Applying the values to the equation,

$\implies\sf (4x + 9)(x -6)=[4x\times x] - [3x\times 6] + [9\times x] - [9\times 6]$

$\implies\sf (4x+9)(x-6)= 4x^2-18x+9x-54$

$\implies\sf (4x+9)(x-6)= 4x^2-9x-54$

Therefore,

$\huge\boxed{\bold{\bf (4x+9)(x-6)= 4x^2-9x-54}}$
