Complete the square for a circle. for #42.

we are given

we can see that

each terms are multiple of 2

so, we can factor out 2

we can divide both sides by 2

we can rearrange it

now, we can move 10 on right side

now, we can add both sides 7^2 and 5^2

we can simplify it

we can also write as

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
