Answer:
Step-by-step explanation:
x^2+8x-3=0 (move constant to other side by adding 3 to each side)
x^2+8x=3 (halve thr linear coefficient, square it and add to each side, (8/2)^2=16)
x^2+8x+16=3+16 (now the left side is a perfect square)
(x+4)^2=19 (now take the square root of each side)
x+4=+-(19^(1/2)) (finally subtract the constant to isolate x by itself)
x= -4+-(19^(1/2))
x=negative four plus or minus the square root of nineteen
According to my calculations. The answer to this question is 89
A IS THE CORRECT ANSWER, IM PRETTY SURE.
Answer:
A) The following are true:
2+4x=2(2x+1)
2+4x=2⋅2x+2⋅1
2+4x=4x+2
2+4x−4x=4x−4x+2
2=2
B)
There are infinitely many solutions.
The equation is an identity
The solution is 2.
The equation is true for all values of x.
