Question

In a family 11 time the number of children's greater than twice the square of the number of the children by 12 how many childrens are there. Please give answer I will made you brain list.

Answer 1

Step-by-step explanation:

11x > 2(x²/12)

11x > x²/6

11 > x/6

x < 66

Answer 2

Answer:

no.of children = 4

Step-by-step explanation:

Acc to question ,

11x-2x²=12                             .....(1)  

-2x²+11x-12=0

It is quadratic equation , so by MTS we can find factors of it .

-2x+8x+3x-12

-2x(x-4)+3(x-4)

Hence factors are (x-4)(-2x+3)

so,x=4and x=3/2

but no.of children can,t be in fraction so ,

x=4 (is suitable)

verify

put value of x in eq (1)

11(4)-2(4)=12

44-32=12

12=12
