Solve. x2 – 2x – 35 = 0 Do you know the answer

x=7     x=-5

Step-by-step explanation:

x^2 – 2x – 35 = 0

Factor

What two numbers multiply to -35 and add to -2

-7*5 = -35

-7+5 = -2

(x-7) (x+5 ) =0

Using the zero product property

x-7 =0   x+5 =0

x=7     x=-5

{7,-5}

Step-by-step explanation: To solve the equation x² - 2x - 45 = 0, factor the left side of the equation to get (x - 7)(x + 5).

To factor x² - 2x - 35, look for factors of -35 that that add to -2.

These factors are -7 and 5.

So now we have (x - 7)(x + 5) = 0.

So either x - 7 = 0 or x + 5 = 0.

Solving for x in each equation, our answer is {7,-5}.
