The identity matrix I_(2)={:[(1,0),(0,1)]:} . If A={:[(2,-3),(5,1)]:} , evaluate AI_(2)=I_(2)A=A

The vertices of a triangle are (5,1), (11,1) and (11,9). Find the co-ordinates of the circumcentre of the triangle.

Ravi calculated 29xx51 and wrote the answer as 1079. Without calculating. Can you find if the answer is correct or not?

Use differential to approximate sqrt(51) .

Factorise : 17a^(6) b^(8) - 34 a^(4) b^(6) + 51 a^(2) b^(4)
