Solve for x: http://i1225.photobucket.com/albums/ee397/motoshifter/125shifter%20-%20Open%20Study/2-29/2.png Thanks
solve the qudratic 5x^2-20x-5=0
x will have two solutions
Were you able to get it to a quadratic form?
5x^2-20x-5=0 is in the quadratic form, I need to factor 20x?
just divide through by 5,and then solve the qudratic x^2-4x-1=0
ans==>x=2-root5 x=2+root5
Take the left part (left of the equal sign) and add using the LCD of 5x 2x + 3 x+5 ------- = ----- now cross multiply 5x 10 20x + 30 = 5x^2 +25x Consolidate \[5x ^{2}+5x-30=0\] Divide thru by 5 getting \[x ^{2}+x-6=0\] Do you know how to solve the quadratic?
Hint, it factors easily. Good luck
sorry bro resolved the problem,turned out to be 5x^2+5x-30=0 then divide through by 5 to get it in radar's form....radar is right
