Question

(a+7)(a-10)+16 factorise

Answer 1

(a+7)(a-10)+16

a(a-10)+7(a-10) +16

a ^2 -10a +7a -70 +16

a^2 - 3a - 54

a ^2 - 9a + 6a - 54

a(a-9)+6(a-9) =0

(a-9)(a+6)=0

(a-9)=0 OR (a+6) = 0

a= 9. 0R a= -6

Answer 2

☀️Hey here is your answer☀️



(a + 7)(a - 10) + 16


$(a + 7)(a - 10) + 16 \\ {a }^{2} - 10a + 7a - 70 + 16 \\ {a}^{2} - 3a - 54 \\ {a}^{2} - 9a + 6a - 54 \\ a(a - 9) + 6(a - 9) \\ (a + 6)(a - 9) \\ \\ i \: hope \: it \: will \: you$


I HOPE IT WILL HELP YOU ☺️☺️
