How do i know if an equation has one solution

WebFeb 8, 2016 · If we take first derivative of f ( x) = x + 2 log ( x ) we have f ′ ( x) = x + 2 x There is one zero of the first derivative at x = − 2 for which f ( − 2) = − 2 + 2 log ( 2) < 0. This … WebExample. Our goal is to find the number of solutions to this quadratic equation: 9 x 2 + 42 x + 49 = 0. Our first order of business is to identify the coefficients a, b, and c (this helps us calculate the discriminant): a = 9, b = 42, c = 49. We’ve identified the coefficients, so we can evaluate the discriminant by substituting these ...

Systems Of Linear Equations With One Solution (3 Ways To Tell)

WebNov 9, 2024 · 9x – 8x = 37 + 35 + 9 = 80 which gives x = 80. Hence, the given linear equation has only one solution i.e. x = 80. From the above examples, we see that the variable x does not disappear after solving & we say that the linear equation will have one solution if it is satisfied by exactly one value of the variable. WebThere can be more than one solution. Example: (x−3) (x−2) = 0 When x is 3 we get: (3−3) (3−2) = 0 × 1 = 0 which is true And when x is 2 we get: (2−3) (2−2) = (−1) × 0 = 0 which is … cannot clean up file history https://autogold44.com
