given (x - 1)(x + 1)(x + 5 ) =0
that is a product of factors equating to zero
to solve equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x + 1 = 0 ⇒ x = - 1
x + 5 = 0 ⇒ x = - 5

Determine k if the expression is a perfect square
A quadratic is of the form;
Where (by comparison):
If the above is a perfect square, then
Substitute values for a, b and c
<em>Hence, k = 4</em>

Answer:
Let 'x' and 'y' be two different numbers.
Leila says that 75% of a number will always be greater than 50% of a number. The inequality that represents this statement is the following:
0.75x > 0.5y
Let x = 100 and y=200. We have that:
0.75(100) > 0.5(200)
75 > 100 ❌ INCORRECT ❌
Given that we found a case in which 75% of a number is not greater than 50% of a number, we can conclude that Leila's claim is incorrect.
