    will those give sum =4 and product = -5 ?

    so, we split the middle term 4x = 5x-x

    x^2+5x-x-5 =0 x(x+5)-1 (x+5) =0 factor out x+5 from that, what u get ?

    ok so im gonna have (x + 5) and also -1

    and there was +x in the beginning also, right ? so , you have (x-1)(x+5) as your denominator, ok ? what about numerator 2x+10 factor out 2, what u get ?

    you can't add 2x to 10 2x has 'x' in it, its variable, 10 is a constant

    2*x+10 = 2*x+2*5 2 is common, factoring it out, 2 (x+5) got this ?

    numerator = 2 (x+5) denominator = (x-1)(x+5) what gets cancelled out ?
