Question

HELP I only have one try and I don't know how to do this!

Please check my work! Is my answer correct?

Answer 1

a and -b

Third answer choice

Explanation:

If (x - a)(x - b) = 0

then one or both of the terms must be zero

Therefore one solution can be found when (x- a) = 0
x - a = 0 ==> x = a

The other solution is when (x+ b) = 0
x + b = 0 ==> x = - b

So the solution set is
x = a and x = -b
