Using suitable identity find 231^222-131^2

Sliva [168]

Given:

Consider the expression is

$231^2-131^2$

To find:

The value of given expression using a suitable identity.

Solution:

We have,

$231^2-131^2$

Using the identity $a^2-b^2=(a-b)(a+b)$ , we get

$231^2-131^2=(231-131)(231+131)$

$231^2-131^2=(100)(362)$

$231^2-131^2=36200$

Therefore, the value of the given expression is $231^2-131^2=36200$ .

20 POINTS AND BRAINLIEST !! PLEASE ANSWER THIS QUESTION !!

BlackZzzverrR [31]

Answer:

-14

Step-by-step explanation:

f(x) = 3x-5

g(x) = -x^2 +1

g(2) = - (2^2) +1

g(2) =-4+1 = -3

Then stick the -3 in f(x)

f(-3) = 3(-3)-5 = -9 -5 = -14

f(g(2) = -14
