Answer
given,
a) x-1=0
adding both side with 1
x = 1
b) x + 1 =0
subtracting both side by 1
x = -1
c) x²- 1 =0
x² = 1
taking square root
x = √1
x = 1
d) x²+ 1 =0
x² = -1
taking square root
x = √-1
x = i (iota)
Answer:
b =± 5 sqrt(3)
Step-by-step explanation:
f(b) = b^2 – 75
To find the roots set the equation equal to zero
b^2 -75 =0
Add 75 to each side
b^2 – 75+75 = 0+57
b^2 = 75
Take the square root of each side
sqrt(b^2) = ±sqrt(75)
b = ±sqrt(3*25)
We know that sqrt(ac) = sqrt(a) sqrt(c)
b = ±sqrt(3)*sqrt(25)
b =± 5 sqrt(3)
