Question

If Zeba was younger by 5 years than what she really is, then the square of her age (in years) would have been 11 more than five times her actual age. What is her age now?

Answer 1

Answer:

Step-by-step explanation:

Let x= Zeba age

As per question given the following equation can be formed:

⇒(x−5)2=11+5x

⇒x2−10x+25=11+5x

⇒x2−10x+25−11−5x=0

⇒x2−15x+14=0

⇒x2−14x−x+14=0

⇒x(x−14)−1(x−14)=0

⇒(x−14)(x−1)=0

x=14 or  x=1

Since her age can't be 1, So it is 14
