Describe the type of solutions for a quadratic equation that has a discriminante of -10

solutions are complex, that is not real

Step-by-step explanation:

The conditions of the solutions from the discriminant are

• If b² - 4ac > 0 then solutions are real and distinct

• If b² - 4ac = 0 then solutions are real and equal

• If b² - 4ac < 0 then solutions are not real

Thus for a discriminant of - 10 the solutions are not real

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
