Factor the quadratic x2+ 3x − 10. Explain your process for factoring and rewrite the original quadratic in factored form
when factoring, our equation should be in this format: (x+__) (x+__) Then we have to find numbers that add up to 3 but multiply to -10 aka -2 and 5. -2+5=3 and -2(5)= -10
The first thing you must do is to find factors that equal to -10 1 x -10, -10 x 1, -2 x 5 and -5x 2. Then of these four groups of factor we chose the one that when the two factors are added equals to 3. So -2 x 5 equals 3 So are answer is (x-2)(x+5)
