18.	Sneha did a math magic with her friend Kriti. She asked her to think of a two-digit number. Then she asked her to add the digits of the number and then multiply the sum by 5. She asked her to add 5 to the product and multiply the result by 2. Then she asked her to divide the result by 10 and to subtract the sum of the digits from this number. Sneha told Kriti that number left is 1. Roti is amazed. Can you help Kriti to understand this magic?
Answer» Answer :- Let the two digits number THINK by kirti was (10X + y) . so, → Digits sum * 5 = 5(x + y) now, → ADD 5 and multiply by 2 = 2{5(x + y) + 5} now, → Divide the result by 10 and subtract the sum of digits = [2{5(x + y) + 5}] / 10 - (x + y) number left is 1. so, → [2{5(x + y) + 5}] / 10 - (x + y) = 1 → (5x + 5y + 5)/5 - (x + y) = 1 → (5x + 5y + 5 - 5x - 5y) = 5 → 5 = 5 (satisfied) .

Sneha told Kriti that number left is 1. Roti is amazed. Can you help Kriti to understand this magic?

Answer»

Answer :-

Let the two digits number THINK by kirti was (10X + y) .

so,

→ Digits sum * 5 = 5(x + y)

now,

→ ADD 5 and multiply by 2 = 2{5(x + y) + 5}

now,

→ Divide the result by 10 and subtract the sum of digits = [2{5(x + y) + 5}] / 10 - (x + y)

number left is 1.

so,

→ [2{5(x + y) + 5}] / 10 - (x + y) = 1

→ (5x + 5y + 5)/5 - (x + y) = 1

→ (5x + 5y + 5 - 5x - 5y) = 5

→ 5 = 5 (satisfied) .

Find the zeroes of the Polynomial P(x) = x2 + 2x - 15 and verify the relationship between thezeroes andcoefficients.

Answer»

Answer:

Given Polynomial : x² + 2x -15

Finding Zeroes:

$: { \implies{ \sf{ {x}^{<klux>2</klux>} + 2x - 15 }}} \\ \\ : { \implies{ \sf{ {x}^{2} - 3x + 5x - 15 }}} \\ \\ : { \implies{ \sf{x(x - 3) + <klux>5</klux>(x - 3)}}} \\ \\ : { \implies{ \sf{(x + 5)(x - 3) = 0}}} \\ \\ : { \implies{ \sf{x = - 5 \: or \: 3}}}$

Relationship between zeroes and coefficients:-

Let us take, ALPHA = -5 and BETA = 3

From the polynomial, x² + 2x - 15

a = 1, B = 2 , c = -15

$\sf \: sum \: of \: zeroes = \alpha + \beta = \frac{ - b}{a} \\ \\ - 5 + 3 = \frac{ - 2}{1} \\ \\ - 2 = - 2$

$\sf product \: of \: zeroes = \alpha \beta = \frac{c}{a} \\ \\ - 5(3) = \frac{ - 15}{1} \\ \\ - 15 = - 15$
