Question

factorize a^2 +15a+26 by using splitting middle term

​

Answer 1

Answer:

= a²+ 15a + 26

sum = 2+13 = 15

product = (2) (13) = 26

= a² + (2+13)a + 26

= a² + 2a + 13a + 26

= (a² + 2a ) + ( 13a + 26)

= a (a+2) + 13 (a+2)

(a+2) is common so Take it out

= (a+2) (a+13)

hence   factorized
