The radicand in the quadratic formula, b squared minus 4 acb2−4ac, is called the discriminant. how many real number solutions will the quadratic equation have if the discriminant is (a) greater than 0, (b) equal to 0, or (c) less than 0?

see explanation

Step-by-step explanation:

• If b² - 4ac > 0 then 2 real, distinct and irrational solutions

• If b² - 4ac = 0 then 2 real and equal solutions

• If b² - 4ac < 0 there are no real solutions

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
