To make a perfect square, we must know that 22/2 = 11. In this case:
(x + 11)^2 = x^2 + 22x + 121
The answer is C
1+1=2
2+2=4
4+3=7
1+4=11
11+5=16
16+6=22
22+7=29.....

Step-by-step explanation:
Answer:
x={-5,-6}
Step-by-step explanation:
x²+11x+30=0
x²+5x+6x+30=0 (as 5*6=30 and 5+6=11)
x(x+5)+6(x+5)=0
(x+5)(x+6)=0
so
x+5=0
x+6=0
therefore
x=-5
x=-6
