Mathematical Equation Test - Special Products And Factors

1) Find the value of x of the following equation: x + 9 = 18.

9

27

-9

18

The equation x + 9 = 18 can be solved by subtracting 9 from both sides of the equation to isolate the variable x. This gives us x = 18 - 9, which simplifies to x = 9. Therefore, the value of x in the given equation is 9.

Explanation

The equation x + 9 = 18 can be solved by subtracting 9 from both sides of the equation to isolate the variable x. This gives us x = 18 - 9, which simplifies to x = 9. Therefore, the value of x in the given equation is 9.

2) Multipy out 2x(a-3)

2ax -6x

-2ax - 6x

2ax + 6x

2ax - 6

The given expression is 2x(a-3). To multiply this out, we can use the distributive property. The 2x is multiplied by both terms inside the parentheses. So, we have 2x times a which gives 2ax, and 2x times -3 which gives -6x. Therefore, the correct answer is 2ax - 6x.

Explanation

The given expression is 2x(a-3). To multiply this out, we can use the distributive property. The 2x is multiplied by both terms inside the parentheses. So, we have 2x times a which gives 2ax, and 2x times -3 which gives -6x. Therefore, the correct answer is 2ax - 6x.

3) Solve for x : 2(x-18) = 2

19

18

38

16

To solve the equation 2(x-18) = 2, we first distribute the 2 to both terms inside the parentheses: 2x - 36 = 2. Then, we add 36 to both sides to isolate the variable: 2x = 38. Finally, we divide both sides by 2 to solve for x: x = 19.

Explanation

To solve the equation 2(x-18) = 2, we first distribute the 2 to both terms inside the parentheses: 2x - 36 = 2. Then, we add 36 to both sides to isolate the variable: 2x = 38. Finally, we divide both sides by 2 to solve for x: x = 19.

4) Factor out : X2 – 6x + 5

(x+5)(x+1)

(x-3)(x-2)

(x-5)(x-1)

(x-5)(x+1)

The given expression, X^2 - 6x + 5, can be factored by finding two numbers that multiply to give 5 and add up to -6. The numbers that satisfy this condition are -1 and -5. Therefore, the expression can be factored as (x - 5)(x - 1).
