Factor x3 + x2 + x + 1 by grouping. What is the resulting expression? (x2)(x + 1) (x2 + 1)(x) (x2 + 1)(x + 1) (x3 + 1)(x + 1)

yanalaym [24]

Answer : $(x^2 + 1)( x + 1)$

Factor $x^3 + x^2 + x + 1$ by grouping

We group first two terms and last two terms

$(x^3 + x^2)+( x + 1)$

Now we take out GCF from each group

GCF of $(x^3 + x^2)$ is x^2

GCF of $+( x + 1)$ is 1

$(x^3 + x^2) +( x + 1)$

$x^2(x + 1) +1( x + 1)$

Now we factor out x+1 that is in common

$(x^2 + 1)( x + 1)$

Which of the point-slope equations below is correct for the line that passes through points (-4,-4) and (1,3)? Check all that ap

netineya [11]

Correct answer is E.

$(-4,-4) \Rightarrow x_1=-4,y_1=-4
\\ (1,3) \Rightarrow x_2=1,y_2=3
\\
\\y-y_1= \frac{y_2-y_1}{x_2-x_1} (x-x_1)
\\
\\ y-(-4)= \frac{3-(-4)}{1-(-4)} (x-(-4))
\\
\\ y+4= \frac{3+4}{1+4} (x+4)
\\
\\y+4= \frac{7}{5}(x+4)$
