Answer:

x^2 + 2x +1  = 2x + 2

Step-by-step explanation:

(x+1) = 2

multiplying both sides by x +1

(x +1) (x+1) = 2 (x+1)

x^2 + 2x +1  = 2x + 2

Answer:

x² + 2x + 1 = 2x + 2

Step-by-step explanation:

Multiply without the multiplication symbol so use distributive property.

(x+1)(x+1) = 2(x+1)

Use the FOIL method (first, outer, inner, last)

(x)(x)+(x)(1)+(1)(x)+(1)(1) = (2)(x)+(1)(2)

which will give you:

x²+x+x+1 = 2x+2

combine like terms

x²+2x+1 = 2x+2

ta da! hope this helps

What is the slope of the line tangent to the curve y+2 = (x^2/2) - 2siny at the point (2,0)?
kirza4 [7]
<span>, y+2 = (x^2/2) - 2sin(y) so we are taking the derivative y in respect to x so we have dy/dx use chain rule on y so y' = 2x/2 - 2cos(y)*y'

</span><span>Now rearrange it to solve for y' y' = 2x/2 - 2cos(y)*y' 0 = x - 2cos(y)y' - y' - x = 2cos(y)y' - y' -x = y'(2cos(y) - 1) -x/(2cos(y) - 1) = y'
</span><span>we know when f(2) = 0 so thus y = 0 so when f'(2) = -2/(2cos(0)-1)
</span><span>2/2 = 1
</span><span>f'(2) = -2/(2cos(0)-1) cos(0) = 1 thus f'(2) = -2/(2(1)-1) = -2/-1 = 2 f'(2) = 2
</span>
