Answer:
x = -5, 2
Step-by-step explanation:
The first step to factor the equation is removing any factors/like terms that all of the variables share.
In the equation , all numbers are multiples of 2, therefore you can factor out 2 from to equation
Next, you can factor the equation in the parenthesis. Since x^2 is not multiplied by anything, you know that the factors of x^2 must be x and x. Therefore, the two factors of -10 must add up to 3. The only two factors of -10/x that add up to 3 are 5 * -2.
The factors of the equation are then (2)(x+5)(x-2)
Lastly, set up only the factors containing a x to 0 in order to solve for x-intercept.
x+5 = 0; x= 0-5 ; x = -5
x - 2 = 0; x = 0 + 2; x = 2
