Web4ac = 0, then equation has two real equal roots, each equal to 2a b (iii) D = b2 4ac < 0, the equation will not have any real root, since square root of a negative real number is not a real number. Thus, a quadratic equation will have at the most two roots. Example 6.6: Without determining the roots, comment on the nature (number of solutions)
WebMay 8, 2024 · The roots are two real numbers that are unequal (they’re not equal to each other), so these are distinct real roots. Which means we’ll use the formula for the general solution for distinct real roots and get???y(x)=c_1e^{-2x}+c_2e^{-3x}??? This is the general solution to the differential equation. WebMar 30, 2024 · The term real root means that this solution is a number that can be whole, positive, negative, rational, or irrational. While numbers like pi and the square root of two are irrational numbers, rational numbers are zero, whole numbers, fractions and decimals. However, the solution to an equation can be real roots, complex roots or imaginary roots.
WebA quadratic equation has real roots when the discriminant is positive or zero (not negative). From an algebra standpoint, this means b2 >= 4ac. Visually, this means the graph of the quadratic (a parabola) touches the x axis at least once. Of course, a quadratic that touches the x axis only once, at the vertex, has one repeated real root ...
WebA quadratic equation has equal roots iff its discriminant is zero. A quadratic equation has equal roots iff these roots are both equal to the root of the derivative. The second hint is easier to apply in this case. .
