25(2x-y)²-81y² factorise . please give an appropriate answer

Answer»

ANSWER :-

$\implies\sf 25(2x - y)^2 - 81y^2$

$\implies\sf [5(2x - y)]^2 - (9y)^2$

$\implies\sf [10x - 5y]^2 - ( 9y)^2$

USING the identity :-

$\sf a^2 - b^2 = (a+b)(a-b)$

$\implies\sf (10x - 5y + 9y)(10x - 5y - 9y)$

$\implies\sf (10x + 4y)(10x - 14y)$

$\boxed{\sf 25(2x - y)^2 - 81y^2 = (10x + 4y)(10x - 14y)}$

VERIFICATION :-

$\sf <klux>LHS</klux> = 25(2x - y)^2 - 81y^2$

$\implies\sf LHS = 25(4x^2 + y^2 - 4xy) - 81y^2$

$\implies\sf LHS = 100x^2 + 25y^2 - 100xy - 81y^2$

$\implies\sf LHS = 100x^2 - 56y^2 - 100xy$

$\sf RHS = ( 10x + 4y)(10x - 14y)$

$\implies\sf RHS = 10x(10x - 14y) + 4y(10x - 14y)$

$\implies\sf RHS = 100x^2 - 140xy + 40xy - 56y^2$

$\implies\sf RHS = 100x^2 - 100xy - 56y^2$

LHS = RHS

Hence verified.

21.

One number is fifteen less than 4 times another. If the sum of the two numbers istwenty, find the two number.

Answer»

Given :-

One number = 15 less than 4 times other
Sum of two numbers = 20

To FIND :-

Both numbers

Solution :-

Let one number be'x' and another number be'y'

then ,

According to question :-

One number = 15 less than 4 times another
x = 4Y - 15. --(1)

Now,

Sum of two numbers = 20

➮ x + y = 20

➮ x = 20 - y --(2)

From (1) and (2) , we get,

➮ 20 - y = 4y - 15

➮ 20 + 15 = 4y + y

➮ 5y = 35

➮ y = 35/5

➮ y = 7

Put y = 5 in (1) , we get,

➮ x = 4y - 15

➮ x = 4(7) - 15

➮ x = 28 - 15

➮ x = 13

Hence,

One number is x = 13
Another number is y = 7

9 term of an Arithmetic Progression is 19.The sum of 4th and 7th term is 24. Find theArithmetic Progression.

Answer»

$\underbrace{\underline{\bf{\bigstar\:Required\:Answer:-}}}$

$\\$

➡ Given :

$\\$

9th Term of the A.P. = 19
4th Term + 7th Term = 24

$\\$

➡ To Find :

$\\$

The Arithmetic Progression (AP).

$\\$

➡ SOLUTION :

$\\$

We know that the $\sf n^{th}$ term of an AP is GENERALISED as -

$\leadsto \: \boxed{ \sf a _{n} =a + (n - 1)d }$

Here,

a = FIRST term of the AP
d = common difference
n = no. of terms
an = n th term

$\\$

$\textit{\textbf{\dag\:According\:to\:the\:Question:}}$

$\\$

$\colon \longrightarrow \sf \: 9 {}^{th} \: term = 19 \\ \\$

$\colon \longrightarrow \sf \: a + 8d = 19 \\ \\$

$\colon \longrightarrow \: \boxed{ \sf{a = 19 - 8d}} \sf \: ...(i) \\ \\$

And..

$\\$

$\colon \longrightarrow \sf \: 4 {}^{th} \: term + {7}^{th} \: term = 24 \\ \\$

$\colon \longrightarrow \sf \: a + 3d + a + 6d = 24 \\ \\$

$\colon \longrightarrow \sf \: 2a + 9d = 24 \\ \\$

From eq(i) , a = 19 - 8d

$\\$

$\colon \longrightarrow \sf \: 2(19 - 8d) + 9d = 24 \\ \\$

$\colon \longrightarrow \sf \: 38 - 16d + 9d = 24 \\ \\$

$\colon \longrightarrow \sf \: - 7d = 24 - 38 \\ \\$

$\colon \longrightarrow \sf \: \cancel{ - 7d }= \cancel{ - 14} \\ \\$

$\colon \implies \underline{ \boxed{ \bf{ \red{d = 2}}}} \: \bigstar$

$\\$

Put it in eq(i)

$\\ \colon \longrightarrow \sf \: a = 19 - 8 \times 2 \\ \\$

$\colon \implies \: \underline{ \boxed{ \bf{ \purple{a = 3}}}} \: \bigstar$

$\\$

$\underline{\dag\:\bf Arithmetic \:Progression :-}$

$\\$

» Arithmetic Progression is in the form :

✒ a , a + d , a + 2d , a + 3d ,...

$\\$

» For this question,

a = 3
d = 2

So,

Required Arithmetic Progression would be :

$\\$

$\sf{ 3,3+2, 3+2\times2, 3+3\times2,...}$

$\\$

$\therefore\underline{\sf A. P. = \pink{3, 5,7,9,...}}$

$\\$
