What are the solutions of the equation? z^2+7z+6=0 a. 1, -6 b. 1, 6 c. -1, 6 d. -1, -6

Option (D) is correct.

The solution of the quadratic equation is -6 and -1

Step-by-step explanation:

Consider the given quadratic equation

We can solve the quadratic equation using middle term splitting method,

7z can be written as z+6z , we get,

Taking terms common, we get,

Thus,

Thus, we get (z+6)= 0 or (z+1)= 0

this gives z= -6 or z= -1.

Thus, the solution of the quadratic equation is -6 and -1

look a the sides they are perpendicular

i can't solve unless i know what the line is
