Factor 3x^2 - 9x - 20 Factor 3x^2 - 9x - 20 @Mathematics

Question

asnaseer · Answer

this cannot be factored - are you sure you have the correct equation?

asnaseer · Answer

the closest I can get are:$$(3x+5)(x-4)=3x^{2}-7x-20$$or$$(3x+4)(x-5)=3x^{2}-11x-20$$

anonymous · Answer

Yeah I have to find x from this equation:
(2 / x - 2) + (7 / x^2 - 4) = (5/x)

asnaseer · Answer

then you need to use the quadratic equation solution to find the two roots of x

anonymous · Answer

I can't use the quadratic equation on the that, the equation i gave is a rational equation

asnaseer · Answer

I just worked out the equation from the new information you gave and it should be:$$3x^{2}-11x-20=0$$

asnaseer · Answer

so solution is:$$(3x+4)(x-5)=0$$which gives x=5 or -4/3

OHH! I got it lol i realized I didnt distribute correctly lol
