Click Blank workbook. This will open the Excel window, from which point you can proceed with enabling Solver. If you have an existing Excel file you'd like to use Solver with, you can open it instead of creating a new file. 3. Click File. It's a tab in the upper-left side of the Excel window. On a Mac, click Tools instead, then skip the next step.
In general, when we solve radical equations, we often look for real solutions to the equations. So yes, you are correct that a radical equation with the square root of an unknown equal to a negative number will produce no solution. This also applies to radicals with other even indices, like 4th roots, 6th roots, etc.
A one-step equation is an algebraic equation you can solve in only one step. Once you've solved it, you've found the value of the variable that makes the equation true. To solve one-step equations, we do the inverse (opposite) of whatever operation is being performed on the variable, so we get the variable by itself. The inverse operations are: When an equation such as -9 - (9x - 6) = 3(4x + 6) has parentheses, we can distribute without changing the value of each side. Then combine like terms. Next, we move all the x-terms to one side and the constants to the other. Finally, we solve for x. Created by Sal Khan and Monterey Institute for Technology and Education. To solve an quadratic equation using factoring : 1 . Transform the equation using standard form in which one side is zero. 2 . Factor the non-zero side. 3 . Set each factor to zero (Remember: a product of factors is zero if and only if one or more of the factors is zero). 4 .If you have a quadratic like y = x² - 2x +1 and a linear equation like y = 2x - 3, this example intersects at one point, x = 2. y = 1 so the point (2,1) is the only solution to this system of equations.
As you may have seen from other replies, for solving such problems you have to divide the equation into "regimes", based on the expression (s) of x that are enclosed in absolute value brackets. Based on your equation, we have three regimes: (i) x >= 1 (ii) 1/2 2x - 1, giving x < 0. Vi1wz0t.
