Answer 1

Answer:

x^2 + (11-2)x - 22

x^2 + 11x - 2x - 22

x (1 + 11) - 2(1 + 11)

(1 + 11) (x - 2)

Answer 2

Answer:

x^2+9x-22=0

x= -b + or- √b^2-4ac÷2a

= -9+ or -√169÷2×1

= -9+ or - 13÷2

x= -9+13÷2 or x= -9-13÷2

= 4÷2 = -22÷2

x =2 x = -11

Step-by-step explanation:

a=1

b=9

c=-22

b^2-4ac=9^2-4×1×-22

= 81+88

=169
