Answer:

Step-by-step explanation:
m = Masa del bloque = 18 kg
F = Fuerza en el bloque = 300 N
= Coeficiente de fricción = 0.6
El equilibrio de fuerzas del sistema viene dado por

La aceleración del bloque es
.
150+3p
p=30
150+3(30)
150+90
240
When p=30 in 150+3p, the final value is 240.
If you are asking what x to the power of 2 minus x is as a mathematical expression, then your answer is:
= x^2 - x
If you are asking what another equivalent expression for x^2 - x is or if you want it in factorised form, then your answer is:
= x ( x - 1 )
