If m and n are the zeroes of the polynomial 6y 2 -7y – 2, find a polynomial whose zeroes are 1/m and 1/n
denis-greek [22]

Answer:

y^2-\frac{7}{2}y+3

Step-by-step explanation:

Given polynomial is,

6y² - 7y - 2

Fro the zeros of the given polynomial,

6y² - 7y - 2 = 0

6y² - 4y - 3y - 2 = 0

2y(3y - 2) - 1(3y - 2) = 0

(2y - 1)(3y - 2) = 0

(2y - 1) = 0

y = \frac{1}{2}

(3y - 2) = 0

y = \frac{2}{3}

Therefore, zeros of this polynomial are m = \frac{1}{2} and n = \frac{2}{3}

If a polynomial has zeros as \frac{1}{m} and \frac{1}{n} then the zeros will be \frac{3}{2} and 2.

Polynomial will be,

(y-\frac{3}{2})(y-2)

= y(y-2)-\frac{3}{2}(y-2)

= y^2-2y-\frac{3}{2}y+3

= y^2-\frac{7}{2}y+3

The line should read 
The large square area = the 4 triangles + the inner square.
(a + b)^2 = c^2 + 4 ( 1/2 * ab)

The positive two-digit integers x and y have the same digits, but in reverse order. Which of the following must be a factor of x
shusha [124]

Answer: (D) 11

Step-by-step explanation:

Let the first digit x composed of ab and the second digit y composed of reversed of ab =ba

The sum of x and y will be

x+y = ab+ ba

x+y= (10.a + b) + (10.b +a)

x+y= 10a+b+10b+a

x+y= 11a+11b

By factorization

x+y= 11(a+b)

Therefore 11 is compulsory factor of x and y
