Question

Show that X=-2 is a solution of 3x(X) + 13x +14=0

Answer 1

7x=14 then finally x=2

Answer 2

The given quadratic equation

3x²+13x+14=0.

Now,

Putting the value of x=-2.

We get,

3x²+13x+14=0

=>3(-2)²+13(-2)+14=0

=>3(4)-26+14=0.

=>12-26+14=0

=>12+14-26=0

=>26-26=0

=>0=0.

Hence x=-2 is the solution of 3x²+13x+14=0.

Hope this help you.
