Answer:
x = 2
Step-by-step explanation:
Since we know one root is -3, we know one factor of the equation is (x+3)
From there we can use the factor we know to factor the rest of the equation:
x^2 + x - 6 = (x+3) * ?
Since know -6 is just 3 * -2 and since 3-2 is 1,
(x+3)(x-2) = x^2 + x - 6
From there,
x - 2 = 0
x = 2
The Answer To This Would 1 : 10 Because You Have To Divide Both By 4 So 4 Divided By 4 Gives You 1 And 40 Divided By 4 Gives You 10
