x = 10
Just plug in the different numbers to see which ones equal 35.
I’m going to plug in x = -8 into the equation
(x - 3)(x - 5) = 35
(-8 - 3)(-8 - 5) = 35 (substitute -8 for x)
(-11)(-13) = 35
143 = 35
This answer is wrong because 143 does not equal 35
Now let’s plug in x = 10
(x - 3)(x - 5) = 35
(10 - 3)(10 - 5) = 35 (substitute 10 for x)
(7)(5) = 35
35 = 35
This solution works because 35 equals 35
