Diketahui suku banyak ƒ(x) = 2x⁴ - 3x² + 5x – 6 dan g(x) = 2x² - 7x + 10. tentukanlah : a. ƒ(x) – g(x) b ƒ(x) + g(x) c. f(x) x g(x)

Langsung aja y

Bagian A
f(x) - g(x) = (2x⁴-3x²+5x-6)-(2x²-7x+10)
f(x) - g(x) = 2x⁴ - 5x² + 12x - 16

bagian B
f(x) + g(x) = (2x⁴-3x²+5x-6)+(2x²-7x+10)
f(x) + g(x) = 2x⁴ - x² - 2x + 4

bagain C
f(x) × g(x) = (2x⁴-3x²+5x-6) × (2x²-7x+10)

= 4x^6 - 6x⁴+10x³-12x²-14x^5 + 21x³-35x²+42x+20x⁴-30x²+50x-60

= 4x^6 - 14x^5 + 14x⁴ + 31x³ - 77x² + 92x - 60

semoga berguna +_+
