Mohon Bantu Jawab Ya…


Diketahui: F(x)= x+1
g(x)= X² + 2x – 3
h(x)= 2x³
Tentukan: 1. f(x).h(x) – g(x)
2. f(x)+g(x) – h(x)

f(x) = (x + 1)

g(x) = (x² + 2x – 3)

h(x) = 2x³

f(x) • h(x) – g(x)

= (x + 1) • (2x³) – (x² + 2x – 3)

= 2x⁴ + 2x³ – x² – 2x + 3

f(x) + g(x) – h(x)

= (x + 1) + (x² + 2x – 3) – 2x³

= x + 1 + x² + 2x – 3 – 2x³

= -2x³ + x² + 2x + x + 1 – 3

= -2x³ + x² + 3x – 2

= – (2x³ – x² – 3x + 2)
