Q.8 A quadratic polynomial with 3 and 2 as the sum and product of its zeros respectively is

Answer»

\bf\huge\blue{\underline{\underline{ Question : }}}

A QUADRATIC POLYNOMIAL with 3 and 2 as the sum and product of its zeros respectively is.

\bf\huge\blue{\underline{\underline{ Solution : }}}

Given that,

  • Sum and Product of zeroes of a Quadratic Polynomial are 3 and 2.

To FIND,

  • Quadratic Polynomial.

Let,

\tt\:\rightarrow Sum\:of\:the\:zeroes : \alpha + \beta = -\cfrac{b}{a}

\tt\:\rightarrow Product\:of\:the\:zeroes : \alpha  \beta = \cfrac{c}{a}

Now,

The form of a Quadratic Polynomial is :

\orange{\bigstar}\boxed{\rm{\red{ x^{2} -(\alpha + \beta)x +\alpha\beta = 0 }}} \orange{\bigstar}

  • Substitute the zeroes.

\sf\:\implies x^{2} - (3)x + 2 =  0

\sf\:\implies x^{2} - 3x + 2 =  0

\underline{\boxed{\rm{\purple{\therefore Hence,\:the\:Quadratic\:Polynomial\:is\:x^{2}-3x+2=0.}}}}\:\orange{\bigstar}

−b

2

=(a+b)(a−b).....(1)

using equation (1) we get

⇒10000x=(9982+18)(9982−18)

⇒10000x=10000(9964)

⇒x=

If A:B = 3:5 & C:D = 4:7, find A:B:C

Answer»

Answer:

Well while solving questions related to ratios,always keep in the mind about the equality between the variables

Consider first case

A:B=5:9

Can also be WRITTEN as 5*4:9*4

Well I just multiplied NUMERATOR and denominator by 4 so actually I multiplied by 1

In the same way B:C can also by multiplied by 9 on both numerator and denominator giving the ratio

B:C =4*9:7*9

Therefore,

A:B=20:36

And B:C=36:49

Since on both ratio B is same

Hence A:B:C=20:36:49

Frame the word problem for the age reletion of you and your grandparents with the condition 5 years later .

Answer»

Question:- the sum of grandfather's and grandson's AGES is 70 years,

5 years LATER, grandfather's age is 5 more than 4 times his grandson's age.

Answers:-

LET grandfather's present age be :- x

let grandson's present age be :- 70-x

5 YEARS LATER

grandfather's age = x+5

grandson's age =75-x

A/Q

x+5= 4(75-x)+5

= x = 300 - 4x

5x = 300

x= 60

grandfather's present age = 60 years

grandson's present age = 70-60

=10 years
