Answer:

I can't solve and show it but only tell a method to do it!

So find the zero of the given factor:

i.e.

$(x + 1) \\ x = - 1$

Now put its value (-1) in the polynomial

${x}^{3} - 13 {x}^{2} + 32x - 20$

Now if the answer comes zero it is a factor.

You'll get your answer!

Which of the following are solutions to the equation below (5x+1)^2=7? Check all that apply.

stiv31 [10]

(5x+1)² = 7; expand: 25x² + 10x +1 = 7 or 25x² + 10x -6 = 0

Solve this quadratic for x:

x = [-b + √(b² - 4ac)]/2a and x = [-b - √(b² - 4ac)]/2a
Plug the values and you'll find :
x = (- √7 - 1)/5 (answer C)
x = (+√7 -1)/5 (answer E)
