Question

Solve.

Answer 1

The problem is set equal to zero.  (x+4)(x+10)=0 Therefore, x= -10, x= -4

Answer 2

Answer:

The solutions are  

                         -4 and -10

Step-by-step explanation:

We are given a quadratic equation in terms of variable x as follows:

$x^2+14x+40=0$

We may solve this question by using the method of splitting the middle term in order to find the value of x from the  equation.

The given equation could be written as:

$x^2+10x+4x+40=0$

Now on taking out the common terms in pair we get:

$x(x+10)+4(x+10)=0\\\\(x+4)(x+10)=0$

                       Hence, we get:

               $x=-4\ and\ x=-10$
