Question

(x-6) (4x+9) give the answer in full steps.....​

Answer 1

Answer:

(x - 6)(4x + 9)

Step-by-step explanation:

(x - 6)(4x + 9)

=> 4x^2 + 9x - 24 - 54 [by multiplying all the terms]

=> 4x^2 - 15x - 54

Now we can further solve it by factorising.

=> 4x - 24x + 9x - 54

=> 4x(x - 6) + 9(x - 6)

=> (x - 6)(4x + 9)

Answer 2

ok¡

sol:

(x - 6) (4x + 9) = 0

x(4x + 9) - 6(4x + 9) = 0

4x^2 + 9x - 24x + 54 = 0

4x^2 - 15x + 54 = 0

This is quadratic equation

4x^2 - 15x + 54 = 0

4x^2 - 24x + 9x + 54 = 0

4x(x - 6) + 9(x - 6) = 0

(4x + 9) = 0 or (x - 6) = 0

4x + 9 = 0 or x - 6 = 0

4x = -9 or x = 6

x = -9/4 or x = 6

I solved by Factorisation method.

Note: u can solve this quadratic equation by formula and Campleting the squre methods.

Thank U
