Question

При каком а уравнение ах+3=0 имеет корень равный -4?

Answer 1

Ах+3=0, при х=-4; -4а+3=0; -4а=-3; а=3/4

Answer 2

Solving the Equation for the Root

To find the value of a for which the equation ax + 3 = 0 has a root equal to -4, we can use the following steps:

1. Substitute the given root -4 into the equation ax + 3 = 0. 2. Solve for the value of a.

Let's proceed with the calculation.

Calculation

Substituting the root -4 into the equation ax + 3 = 0:

-4a + 3 = 0

Now, solving for the value of a:

-4a = -3

a = -3 / -4

a = 3 / 4

So, the value of a for which the equation ax + 3 = 0 has a root equal to -4 is a = 3/4.
