Which quadratic equation is equivalent to (x + 2)2 +5(x + 2) – 6 = 0?
(u + 2)2 + 5(u + 2) – 6 = 0 where u = (x - 2)
u2 + 4 + 5u - 6 = 0 where u = (x - 2)
02 + 5u - 6 = 0 where u = (x + 2)
02 + -6 = 0 where u = (x + 2)

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
