Answer 2

Answer:

• Question -:

$(20²+9)(20²+5)$

• Concept -:

First find the square of 20 . Then , add the following after adding just multiply both the value which will come .

Because after coming out of the bracket if any of the sign will not there then multiply.

And also use the BODMAS formula :

B = Brackets

O = Of

D = Division

M = Multiplication

A = Addition

S = Subtraction

• Solution -:

$\implies{(20²+9)(20²+5)}$

$\implies{(20×20+9)(20×20+5)}$

$\implies{(400+9)(400+5)}$

$\implies{409×405}$

$\implies{165645}$

___________________________

If the question is (2a²+9)(2a²+5)

Then ,

= (2a²+9)(2a²+5)

Change their position a² and the normal number .

= 2a²+2a²+9+5

= 4a²+14

• Answer -:

So , the answer of (20²+9)(20²+5) = 165645

So , if the question is (2a²+9)(2a²+5) .

Then , the answer is 4a²+14 .
