Find a degree 3 polynomial having zeros -5, 1 and 5 and the coefficient of x^3 equal 1

mote1985 [20]

Answer:

$x^3 -x^2 -25x +25$

Step-by-step explanation:

$\text{The roots are,}~ \alpha = -5,~ \beta = 1 ~ \text{and}~ \gamma = 5\\\\\text{The polynomial is,}\\\\~~~x^3 - (\alpha + \beta + \gamma)x^2+(\alpha \beta + \beta \gamma+ \gamma \alpha)x - \alpha\beta \gamma\\\\=x^3 - (-5+1+5)x^2 +(-5 \cdot 1 + 1 \cdot 5 + 5 \cdot -5)x - (-5)(1)(5)\\\\=x^3 -(0+1)x^2 + (-5+5-25)x +25\\\\=x^3 -x^2 -25x +25$

Find to numbers, A & B,whose Products, A x B, is less than the sum, A + B. Can you find to positive numbers?

NeTakaya

Answer:

any number, n, multiplied by 1 is less than n + 1, so A = 1, B = any number

For example, 1 % 7. 1 * 7 = 7. 1 + 7 = 8

Also, having one of the variables be a decimal can make the numbers smaller.

For example, 28 * 0.5 = 14. 28 + 0.5 = 28.5
