Answer:
x1=(-4+5i)/2
x2=(-4-5i)/2
Step-by-step explanation:
4x^2 +16x+49=8
4x^2+16x+49-8=0
4x^2 +16x+41=0
a=4, b=16, c=41
x1=(-b+sqrt(b^2-4ac))/2a
x2=(-b-sqrt(b^2-4ac))/2a
x1=(-16+sqrt(16^2-4*4*41))/2*4
x1=(-16+sqrt(256-656))/8
x1=(-16+sqrt(-400))/8
x1=(-16+20i)/8
x1=(-4+5i)/2
x2=(-4-5i)/2
Answer:
or what values of x would this function be difficult to compute in a computer; x is approximately zero.
The best way to avoid the difficulty is to solve for the inverse of the expression given ,i.e solve for f(x) = 1 / √x2+ 2x+ 2−x−1.
Step-by-step explanation:
The detailed steps is as shown in the attached file.
Your answer would be <span><span><span><span>5−7</span>+6</span>−3</span>−1</span>−<span>(<span>−8</span>) = 8</span>
The average is 80*
80* + 80*=160 divided by 2 is 80*
