Question

Which number, when multiplied by another number greater than it by 3, gives a product 12 short of 100.​

Answer 1

Answer:

5.33

Step-by-step explanation:

x×3x =100-12

3x^2 =88

x^2= 88/3

x^2=29.3

x =

$\sqrt{29.3}$

=5,3

Answer 2

Answer:

Let the numbers be x and x+3

According To The Problem,

x(x+3) = 100-12 [ As it's given that the product is a number is 12 less than 100]

or x^2 + 3x = 88

or x^2 + 3x - 88 = 0

or x^2 + 11x - 8x - 88 = 0

or x(x+11) - 8(x+11) = 0

or (x+11) (x-8) =0

Therefore, x has two values, 8 or -11

The number is 8
