How would you figure out (b x b) +3= 4B?

Question

I need help on this problem!

Answer 1

Is it 4B or 4b?  If it's 4B there's nothing you can do to figure it out.  If it's 4b, then it's:

b² - 4b + 3 = 0

(b - 3)(b -1) = 0

So, b-3 = 0 and/ or b-1 = 0

b = 3 and/ or b = 1

Answer 2

b^2 +3=4b

b^2-4b+3=0

(b-1)(b-3)=0

b-1=0

b=1

b-3=0

b=3

hope this helps

Answer 3

b x b= b^2, so you get

b^2+3=4b

Subtract 4b from each side, and you get b^2-4b+3=0

You can factor it out:

(b-3)(b-1)=0

Then you get b=3 and b=1.

The answers are 3 and 1.

Hope this helps!
