Answer:
because P(x) has factors of (x-2) and (x+1) => x = 2 and x = -1 are the solutions of P(x)
so we have:

=> 
With P(x) = 0
=> 
=> ........

Answer:

Step-by-step explanation:
3(x - 4) = 11x
Expand the brackets:
3x - 12 = 11x
Subtract 3x from both sides to isolate the -12:
3x - 12 = 11x
3x - 3x - 12 = 11x - 3x
-12 = 8x
8x = -12
Divide both sides by 8:
