Question

Evaluate:x-2 -100 (x-1)2,if X=2.2​

Answer 1

Step-by-step explanation:

[2.2]^2 - 100 [2.2-1]^2 [ putting the value of x = 2.2] ,

4.84 - 144 = -139.16

Answer 2

Answer:

The value of $x-2 -100 (x-1)2$ is -239.8 .

Step-by-step explanation:

Given -

x = 2.2

To find -

The value of $x-2 -100 (x-1)2$

Solution -

Given,

$x-2 -100 (x-1)2$

Put the given value of x in these equation

= $2.2-2 -100 (2.2-1)2$

For simplifying we will use BODMAS,

As per BODMAS rule,

B for Bracket

O for Of

D for Divide

M for Multiply

A for Addition

S for Subtraction

1. solve the bracket

= $2.2-2 -100 (1.2)2$

2. Multiply

= $2.2-2 -200 (1.2)$

= $2.2-2 -240.0$

3. Addition

two - becomes addition

= $2.2 -242$

= $- 239.8$

∴ The value of $x-2 -100 (x-1)2$ is -239.8 .
