**How to solve 0.5x-0.2x+0.4x=14 Quora**

4.2 Solving 7x 2-5x-2 = 0 by Completing The Square . Divide both sides of the equation by 7 to have 1 as the coefficient of the first term : x 2-(5/7)x-(2/7) = 0 Add 2/7 to both side of the equation : x 2-(5/7)x = 2/7... #0 = x^2+5x+4# #color(white)(0) = (x+4)(x+1)# Substitution is more useful when one of the given equations uses the substituted variable in a more complicated way.

2007-11-25 · Best Answer: First: eliminate parenthesis - use the Foil method... -2(x)-2(- 5) + 7 = x - 8 - 5x -2x+10 + 7 = x - 8 - 5x -2x + 17 = - 4x - 8 Sec: combine "like" terms - add 4x to both sidse (when you move a term to the opposite side, always use the opposite sign). -2x + 17+4x = - 4x +4x- 8 -2x + 17+4x = - 8

- 2008-06-10 · Best Answer: Question Number 1 : For this equation 7*x^2 + 5*x + 8 = 0 , answer the following questions : A. Find the roots using Quadratic Formula ! Answer Number 1 : The equation 7*x^2 + 5*x + 8 = 0 is already in a*x^2+b*x+c=0 form. So we can imply that the value of a = 7, b = 5, c = 8…
- 2003-05-27 · By definition, if x b = a then log a = x b In this case, if x 2 = 8 then log 8 = x 2 To find a logarithm, you would typically use a calculator or table of logarithms (in much the same way that you'd find the sine or cosine of an angle, and for much the same reason). The fly in the ointment is that most calculators and log tables assume that your base (i.e., 'b' in the description above) is
