If (x + 5)(x - 2) = 18, then which of the following statements is true?

a.) x + 7 = 0 or x - 4 = 0
b.) x + 5 = 0 or x - 2 = 0
c.) x + 5 = 6 or x - 2 = 3

The correct answer is option A.

Step-by-step explanation:

(x + 5)(x - 2) = 18

Using identity :

x = x, a = 5, b = -2

Using Middle term splitting method to factorize:

So, we have two solutions of x:

1)

2)

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
