Question

Factorise a²-19a-92​

Answer 1

Question:-

➡ Factorise a² - 19a - 92

Answer:-

➡ The factorised form is (a + 4)(a - 23)

Solution:-

a² - 19a - 92

= a² - 23a + 4a - 92

= a(a - 23) + 4(a - 23)

= (a + 4)(a - 23)

Hence, the factorised form is (a + 4)(a - 23)

Answer 2

Answer:

a^2+4a-23a-92

a(a+4)-23(a+4)

(a-23)(a+4)

a-23=0 a+4=0

a=23,a=-4
