Answer and Step-by-step explanation:
polynomial P with the lowest possible degree
solutions: a)−2, 3,−4i,4i b)−1, 3i c)0,2,1 +i,1-i
The polynomial with the lowest degree that has the given solutions is a multiplication of the monomials (x-solution). And with complex roots, we always have a number and its conjugate
a)−2, 3,−4i,4i
P(x) = (x-(-2))*(x-3)*(x-(-4i))*(x-4i) = (x+2)(x-3)(x-4i)(x+4i) = (x²-3x+2x-6)(x²-16i²) = (x²-x-6)(x²+16) = x⁴+16x²-x³-16x-6x²-96 = x⁴-x³+10x²-16x-96
b)−1, 3i
(x-(-1))*(x-3i)*(x-(-3i)) = (x+1)(x-3i)(x+3i) = (x+1)(x²-9i²) = (x+1)(x²+9) = x³+9x+x²+9
c) 0,2,1 +i,1-i
(x-0)(x-2)(x-(1+i))(x-(1-i)) = x(x-2)(x-1-i)(x-1+i) = (x²-2x)(x²-x+xi-x+1-i-xi+i-i²) =
(x²-2x)(x²-x-x+1+1) = (x²-2x)(x²-2x+2) = x⁴-2x³+2x²-2x³+4x²-4x = x⁴-4x³+6x²-4x
Find the greatest common factor of both numbers:
Factors for 150:
150: 1, 2, 5 , 6, 10, 15, 25, 30, 50, 75, 150
Factors for 270:
1, 2, 3, 5, 6 , 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
The largest number they both have in common is 30, so the largest tile could be 30 cm^2.
Answer:
(0,2)
Step-by-step explanation:
2:4 means one part is 2/(2+4)=1/3 of AB and the other part is 2/3 of AB
Add 1/3 of the distance from -2 to 4. (1/3)(4+2)=2. -2+2=0 The x coordinate is 0
Subtract 1/3 of the distance from 6 to -6, (1/3)6+6)=4 6-4=2 The y coordinate is 2
The point is (0,2)
