What is the meaning of a negative rational number?

Mathematics
1 answer:
Alja [10]3 years ago
6 0

A rational number, by definition, is a number formed as the ratio of two integers. For example: 3/4 is a rational number. So is 1/51.

A negative rational number is precisely the same, except that we preface it with the negative sign. For example: -3/4, -1/51

quester [9]

Answer:

x=3,5

Explanation:

x2−8x+15=0

Try to express the terms of the equation in square form.

Adding 16 both sides of the equation,

(x2−2⋅x⋅4+42)+15=16

or,(x−4)2+15−16=0

or,(x−4)2−1=0

or,(x−4)2−12=0

This is the a2−b2=(a+b)(a−b)form.

(x−4+1)(x−4−1)=0

or,(x−3)(x−5)=0

Now, equate both the terms to zero since both of them when multiplied, give zero.

Either,

x−3=0

∴x=3

Or,

x−5=0

∴x=5

Ans:x=3,5 Hope this helpsXD...!!
