Witam. Mógłby ktoś rozwiązac mi poniższe zadania? Bardzo was prosze.
1. Uporządkuj wielomian w i podaj jego stopień.
a) w(x) = x + x ³ + x ⁵ - 1 - x ² - x ⁴
b) w(x) = 2x ⁶ - x ³ + 2/3x ⁴ - x - 3/2x ⁵
c) w(x) = 3x ⁴ - 2 + 6x - x ² + x ⁷ + 2x ⁸
d) w(x) = 5 - 1/2x + 2x ¹⁰ - x ⁶ + 3x ²
2. Oblicz wartość wielomianu w dla : x = 0, x = 1, x = -1, x = 2. x = -2
a) w(x) = 2x ³ - x ² + x - 4
b) w(x) = x ⁴ + 2x ³ - 6x + 1
c) w(x) = x ⁵ - x ² + 3x - 2
d) w(x) = -x ⁶ + 2x ³ - x + 3
3. Oblicz wartość wielomianu w dla : x = 0, x = 1, x = 2. x = -3
a) w(x) = 3x ³ + x ² - 2x - 3
b) w(x) = -2x ³ + x ² - 5x + 2
c) w(x) = x ³ - 4x ² + 3x - 4
d) w(x) = -x ⁴ + 5x ³ - 4x - 10

1. Uporządkuj wielomian w i podaj jego stopień.
a) w(x) = x + x ³ + x ⁵ - 1 - x ² - x ⁴
W(x) = x⁵ - x⁴ + x³ -x² + x - 1 - wielomian piątego stopnia
b) w(x) = 2x ⁶ - x ³ + 2/3x ⁴ - x - 3/2x ⁵
W(x) = 2x⁶ - 3/2x⁵ + 2/3x⁴- x³ - x - wielomian szóstego stopnia
c) w(x) = 3x ⁴ - 2 + 6x - x ² + x ⁷ + 2x ⁸
W(x) = 2x⁸ + x⁷ + 3x⁴ - x² + 6x - 2 - welomian ósmego stopnia
d) w(x) = 5 - 1/2x + 2x ¹⁰ - x ⁶ + 3x ²
W(x) = 2x¹⁰ - x⁶ + 3x² - ½x + 5 - wielomian dziesiatego stopnia
2. Oblicz wartość wielomianu w dla : x = 0, x = 1, x = -1, x = 2. x = -2
a) w(x) = 2x³ - x² + x - 4
W(0) = -4
W(1) = 2 - 1 + 1 - 4 = -2
W(-1) = -2 -1 -1 - 4 = -8
W(2) = 16 - 4 + 2 - 4 = 10
W(-2) = -16 - 4 - 2 - 4 = -26
b) w(x) = x⁴ + 2x³ - 6x + 1
W(0) = 1
W(1) = 1 + 2 - 6 + 1 = -2
W(-1) = 1 - 2 + 6 + 1 = 6
c) w(x) = x⁵ - x ² + 3x - 2
W(0) = -2
W(1) = 1 - 1 + 3 - 2 = 1
w(-1) = -1 + 1 - 3 - 2 = -5
W(2) = 32 - 4 + 6 - 2 = 32
W(-2) = -32 - 4 -6 -2 = -44
d) w(x) = -x⁶ + 2x³ - x + 3
W(0) = 3
W(1) = -1 + 2 + 1 + 3 = 5
W(-1) = -1 -2 - 1 + 3 = -1
W(2) = -64 + 16 - 2 + 3 = -47
W(-2) = -64 - 16 + 2 + 3 = -75
3. Oblicz wartość wielomianu w dla : x = 0, x = 1, x = 2. x = -3
a) w(x) = 3x³ + x² - 2x - 3
W(0) = -3
W(1) = 3 + 1 - 2 - 3 = -1
b) w(x) = -2x³ + x² - 5x + 2
W(0) = 2
W(1) = -2 + 1 - 5 + 2 = -4
c) w(x) = x³ - 4x² + 3x - 4
W(0) = -4
W(1) = 1 - 4 + 3 - 4 = -4
d) w(x) = -x⁴ + 5x³ - 4x - 10
W(0) = -10
W(1) = 1 + 5 - 4 - 10 = -8
