WebIf the discriminant is greater than 0, we expect this many real number solutions: If the discriminant is equal to 0, The radicand in the quadratic formula, b squared minus 4 ac , 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? Let us recall the general solution, α = (-b-√b2-4ac)/2a and β = (-b+√b2-4ac)/2a 1. Case I: b2– 4ac > 0 When a, b, and c are real numbers, … Meer weergeven α = (-b-√b2-4ac)/2a and β = (-b+√b2-4ac)/2a Here a, b, and c are real and rational. Hence, the nature of the roots α and β of equation ax2 + bx + c = 0 depends on the quantity or expression (b2 – 4ac) under … Meer weergeven Example 3: Determine the value(s) of p for which the quadratic equation 2x2 + px + 8 = 0 has equal roots: A) p = ±64 B) p = ±8 C) p = ±4 D) p … Meer weergeven jcpenney goldsboro north carolina

The easiest way to think about this is the percent of people you beat. i.e. Your height is in the 90% it means you are taller than 90% of the population studied. If you got a 90% on the test did you score in the 90 percentile? NO. All that means is that you got a 90%. lutheran quilts
