Answer:
first expression = 12x^4+324x
=12x(x^3+27)
=12x(x^3+3^3)
=12x(x+3)(x^2-3x+9)
second expression = 36x^3+90x^2-54x
=18x(2x^2+5x-3)
=18x(2x^2+6x-x-3)
=18x(x+3)(2x-1)
HCF = 6x(x+3)
LCM = 36x(x+3)(2x-1)(x^2-3x+9)

Step-by-step explanation:
12×4=48+324=372
36×3=108+90×2=180
108+180=288-54=234
After that,we do h.c.f
372÷234=138,234÷138=96,138÷96=42,96÷42=12,12÷6=2.
