Polynomial and Rational Functions CHAPTER 3 294 37-46 - Finding a Polynomial with Specified Zeros Find a polynomial with integer coefficients that satisfies the given conditions. 37. P has degree 2 and zeros 1 + i and 1 -i. – ¡V2. 38. P has degree 2 and zeros 1 + iV2 and 1 39. Q has degree 3 and zeros 3, 2i, and –2i. 40. Q has degree 3 and zeros 0 and i. .41. P has degree 3 and zeros 2 and i. 42. Q has degree 3 and zeros –3 and 1 + i. 43. R has degree 4 and zeros 1 - 2i and 1, with 1 a zero of multiplicity 2. 44. S has degree 4 and zeros 2i and 3i. 45. T has degree 4, zeros i and 1 + i, and constant term 12. 46. U has degree 5, zeros , –1, and -i, and leading coefficient 4; the zero -1 has multiplicity 2. 2 47–64 - Finding Complex Zeros polynomial. Find all zeros of the 47. P(x) = x³ + 2x? + 4x + 8 %3D 48. P(x) = x³ – 7x² + 17x – 15 49. P(x) = x³ - 2x2 + 2x - 1 50. P(x) = x³ + 7x2 + 18x + 18 51. P(x) = x³ - 3x2 + 3x – 2
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
