Best ResponseYou've already chosen the best response.0there are 4+ method to factor quadratic equation for this question AC method (headphone) would easy where you have to find `2` numbers when you `multiply` them you should get product of `AC` and when you `add` or subtract them you should get `middle` term

Best ResponseYou've already chosen the best response.0\[\huge\rm Ax^2+Bx+C=0\] a=leading coefficient b=middle term c= constant term what is a and c in that eqaution ?

Best ResponseYou've already chosen the best response.0nice leading coefficient is one \[\rm 1x^2+4x12\] so what two number you should multiply to get 12 but when you add them you should get 4

Best ResponseYou've already chosen the best response.0no. factors are (x+ first number)(x+2nd number) set it equal to zero remember one of them is negativve
