Question

how many roots does 2x -5=2 have ?

Answer 1

Answer:

ok

Step-by-step explanation:

Here, 2x = 2+5

so, 2x = 7

thus x = 7/2

which is 3.5

Answer 2

One root.

Step-by-step explanation:

Let us find the roots of the given equation.

⇒ 2x - 5 = 2

⇒ 2x = 2 + 5

⇒ 2x = 7

⇒ x = 7/2

Therefore, the root of the equation 2x - 5 = 2 is 7/2.

There is only one root in this equation. Since, the given equation is linear, has the highest degree (power) as 1, it has only one root.

Know more:

• Quadratic equation: These kind of equations has two roots, since the highest degree is 2.
• Cubic equation: These kind of equations has three roots, since the highest degree is 3.

Note:

• Sometimes, an equation has no roots!
