Best ResponseYou've already chosen the best response.04x2 = 12x + 40 4x^2  12x  40 = 0 Get rid of 4 by taking commons 4(x^2 3x  10) = 0 Divide 4 on both sides (x^2 3x  10) = 0 Now factor: x^2  3x 10 =0 x^2 5x + 2x  10 = 0 take commons: x(x5) +2(x5) = 0 (x+2)(x5) = 0 solve them for Zero: x = 2 x = 5

Best ResponseYou've already chosen the best response.1taking 4 common on both sides.. x^2 = 3x + 10 x^2  3x  10 = 0 now factorize x^2 5x + 2x  10 = 0 x(x5) +2(x5) = 0 (x5)(x+2)=0 Either (x5)=0 this gives x=5 Or (x+2)=0 this gives x= 2
