SOLUTION: Please help me solve for x in this equation: {{{ -4x^2=9x }}} add 4x^2 to both sides of the equation to obtain 4x^2 +9x =0 Factor out an x to obtain x(4x+9)=0 Set each term

Question 879751: Please help me solve for x in this equation:

add 4x^2 to both sides of the equation to obtain
4x^2 +9x =0
Factor out an x to obtain
x(4x+9)=0
Set each term to 0 and solve each for x
x =0 and 4x+9=0
in the equation 4x+9=0 subtract 9 on both sides of the equation to obtain
4x= -9
Divide both sides by 4
4x/4 = -9/4
x= -9/4
Therefore x=0 amd x= -9/4
