Answer:
lesser x = -9, greater x = 10
Step-by-step explanation:
To factor the left side, we need to find two numbers that have a sum of -1 and a product of -90. These numbers are -10 and 9, therefore, the factored version of the left side will be (x - 10)(x + 9). The equation then becomes (x - 10)(x + 9) = 0. Next, we can use the Zero Product Property:
x - 10 = 0 or x + 9 = 0
x = 10 or x = -9
