3x^3+ 8x^2- 9x + 2 is an example. You can't use grouping to factor out a GCF in a way that would produce a common factor. In order to explain how this works, you need to know that when solving an equation by factoring, you need to set the factored out thing equal to 0 and...
Check whether the equation is factorable. You can factor a binomial that has a greatest common factor, is a difference of squares, or is a sum or difference of cubes. Equations such as x + 5 = 0 can be solved without factoring. Sums of squares, such as x^2 + 25 = 0, are not ...
During an impact, the energy of a moving object is converted into work, and force plays an important role. To create an equation for the force of any impact, you can set the equations for energy and work equal to each other and solve for force. From there, calculating the force of an...
Back to top6.1 Explaining formulaStep 1 - Multiplying corresponding components in the given arraysThe first logical expression B2:B8=B10 uses an equal sign to check if the values in cell range B2:B8 are equal to the value in cell B10....
Sometimes it is necessary to factor quadratic expressions, in order to solve them or just to rewrite them in a way that is easier to use. Factoring is the process of finding the factors of something.Answer and Explanation: Quadratic expressions are equations which have the form ax2+bx+c=0...
Solving the equations for an overdetermined model uniquely is not possible. To create a unique solution that is meaningful, we apply a constraint so that the coefficients for each factor sum to 0. In this case these are beta(2)...beta(4). The interpretation of the solution is then...
How do you solve the inequality (x^2 - 16) / (x^2 - 4x - 5) is greater or equal to 0?Solving Inequality:To solve a rational inequality, we can use the factors of the numerator and denominator and test the values.. So, we also need to know how to fa...
The second term on the right-hand side of the equation above contains the electroneutrality condition as a factor, which is equal to zero. The factor within parentheses in the first term on the right-hand side of the equation above is equal to the electrolyte conductivity, ...
In order to convert from milligrams to mmol, you will need to make use of the molar mass of the substance in question. Since the molar mass is given in grams per mol (g/mol) you will also need to take into account that there is a conversion factor from milligrams to grams (there ar...
