Question

Factorise each expression using algebraic identities
K^2+169+26K​

Answer 1

Answer:

k² +26 k + 169

Here Sum = 26 k = 13k+ 13k

Product = 169 k² = 13k × 13k

So 13k amd 13k satisfy the equation.

Put 13k +13k in place of 26k.

=k² +13k +13k +169

=k(k+13) +13(k+13)

=(k+13)(k+13)

Answer 2

Answer:

K^2 + 26k + 169

k^2 + 13k +13k+ 169

k(k+13)+ 13(k+13)

(k+13) (k+13)
