Question

factories a^2 +ab+7a +7b​

Answer 1

Answer :

• a² + ab + 7a + 7b = (a + 7) (a + b).

Given :

• a² + ab + 7a + 7b

To Factorise :

• a² + ab + 7a + 7b

Solution :

↦ a² + ab + 7a + 7b

↦ a² + 7a + ab + 7b

↦ a(a + 7) + b(a + 7)

↦ (a + 7) (a + b)

Hence , a² + ab + 7a + 7b = (a + 7) (a + b).
