Question

Solve. x^2 – 9x = –14

x = 2 and x = –7

x = 2 and x = 7

x = –2 and x = –7

x = –2 and x = 7

Answer 1

(x-2)(x-7)
x= 2,7

Answer 2

x = 2 and x = 7

Answer 3

x^2 – 9x = –14
x^2-9x+14=0
x^2-2x-7x+14=0
x(x-2)-7(x-2)=0
(x-2)(x-7)=0
=>x=2,7

Answer 4

x = 2 and x = 7
x^2 – 9x = –14
x^2 – 9x +14=0
x^2-7x-2x+14=0
(x-7)(x-2)=0

Answer 5

\[x ^{2}-9x=-14\]

Answer 6

\[x ^{2}-9x+14=0\]

Answer 7

(x-7)(x-2)=0
x=7,2
