Answer:
b.9
Step-by-step explanation:
21. x² - 81 = 0A. 1B. 9C. -9D. -81
Answer:
The answers are both B & C.
Step-by-step explanation:
*Transpose the -81 to the other side of the equation:
[tex]x^{2}[/tex]=81 -> Take note the sign changes when you transpose a term on the other side of the eqaution
*Extracting the square root from both sides of the equation:
[tex]\sqrt{x^{2}[/tex]=[tex]\sqrt{81}[/tex]
This will give the answer of
x=+/- 9 (positive, negative 9)
Since that is [tex]x^{2}[/tex], we have 2 values of x, +9 and x=-9

Carry on learning
Step-by-step explanation:
Hope it helps guys
Answer:
A. x² – 81
Step-by-step explanation:
The answer is letter A, x² – 81.
We can simply solve this problem by applying the FOIL Method;
(x + 9) (x – 9): First ; x*x = x²
(x + 9) (x – 9): Outer ; x*(-9) = -9x
(x + 9) (x – 9): Inner ; 9*x = 9x
(x + 9) (x – 9): Last ; 9*(-9) = -81
Combine: x²-9x+9x-81
Combine like terms: x²(-9x+9x)-81
= x² – 81
Shorter way:
If the problem is like this (a+b) (a-b) then the faster way to solve it is by skipping 2 parts in FOIL Method and just do the First and the Last but take note, only use this if the equation of your problem is like this: (a+b) (a-b)
28. Which of the following is the product of the given expression (x + 9) (x – 9)? A. x² – 81 B. x² + 81 C. 2x² – 81 D. 2x² + 81
