Question

If zeba were 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

#BAL

Let Current age of Zeba = x years

Zeba's age If She is younger by 5 years  = x -5

According To Question

(x-5)2 = 11 + 5x

=> x2 + 25 -10x = 11 + 5x

=> x2 -15x + 14=0

=> x2 -14x-x+14=0

=> x (x-14) -1(x-14)=0

=> (x-1)(x-14)=0

=> x - 1=0 or x-14=0

=> x = 1, 14

x can't be 1.

So current age of Zeba = 14 years

Answer 2

Answer:

14 Years

Step-by-step explanation:

Let Current age of Zeba = x years

Zeba's age If She is younger by 5 years  = x -5

(x-5)2 = 11 + 5x

=> x2 + 25 -10x = 11 + 5x

=> x2 -15x + 14=0

=> x2 -14x-x+14=0

=> x (x-14) -1(x-14)=0

=> (x-1)(x-14)=0

=> x - 1=0 or x-14=0

=> x = 1, 14

x can't be 1.

So current age of Zeba = 14 years
