quadratic formula by using factoring method



Sagot :

do you mean quadratic equation using factoring method? 
ex.
x²-3x=10 just tranpose those on the right to the left
x²-3x-10=0
then look for the factors of x²... so it will be
(x    )(x    )=0 then look for factors of -10 ...that when you multiply them you will get -10 and when you add them you will get -3... so the factors are -5 and +2

so the answer there is
(x-5)(x+2)=0
.Simplifying by adding its like terms and breaking down them by squaring.
