Question

*Which of these polynomials has 2 as its zero?*

1️⃣ 8x + 12
2️⃣ 8x - 12
3️⃣ 4x + 8
4️⃣ 5x - 15​

Answer 1

Concept:

First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. For instance, 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3 are examples of linear equations.

Given:

8x + 12

8x - 12

4x + 8

5x - 15​

Find:

Which of these polynomials has 2 as its zero?

Solution:

1) 8x + 12=0

   ⇒x=-3/2

2) 8x - 12=0

⇒x=3/2

3) 4x + 8=0

 ⇒x=-2

4) 5x - 15​=0

   ⇒x=3

Therefore, no polynomials. has one of the zeroes as 2
