Answer:
2(xy + 2)(x + 1) (C)
Step-by-step explanation:
2x^2y + 2xy + 4x + 4
= 2xy(x + 1) + 4(x + 1)
= (2xy + 4)(x + 1)
= 2(xy + 2)(x + 1)
Answer:
Step-by-step explanation:
cd(x) would equal c(x) multiplied by d(x) so we get = .
The domain of is anything except 2, so the domain of (cd)(x) is (-inf, 2) U (2, inf).
So first we have to find out what the bottom number is so
8x+14
subsitute 8 for x
8(8)+14
64+14
78
so 156/78
an easy way to do this is to factor it out and find the 'ones' like 4/8=1/2 times 4/4 (4/4=1 and can be canceled out)
*=times
156=2*2*3*13
78=2*3*13
so (2*2*3*13)/(2*3*13)
2/1 times (2*3*13)/(2*3*13)
we can cross out the (2*3*13) and get
2 as the answer
Complete the SquareSolve for x over the real numbers:(x - 8)^2 - 100 = 0
Add 100 to both sides:(x - 8)^2 = 100
Take the square root of both sides:x - 8 = 10 or x - 8 = -10
Add 8 to both sides:x = 18 or x - 8 = -10
Add 8 to both sides:Answer: x = 18 or x = -2
