(x-12)(x-1) is the answer.
Answer:
{4 + 2√3, 4 - 2√3} thus the solution is A. x = 4 + 2 sqrt(3) or x = 4 - 2 sqrt(3)
Step-by-step explanation:
Solve for x over the real numbers:
(x - 4)^2 = 12
Take the square root of both sides:
x - 4 = 2 sqrt(3) or x - 4 = -2 sqrt(3)
Add 4 to both sides:
x = 4 + 2 sqrt(3) or x - 4 = -2 sqrt(3)
Add 4 to both sides:
Answer: x = 4 + 2 sqrt(3) or x = 4 - 2 sqrt(3)
The number 144 is rational because it can be expressed by 144/1
Answer:Its O.x^2-4x-21
Step-by-step explanation:
(x-7)(x+3)we multiplie one value with anothet in different brackets and we get x^2+3x-7x-21,add same constant with x and u get .O
