(z-8) (z+2)
What I do to factor is find _x_=-16 and _+_=-6. -8x2=-16 and -8+2=-16. The coordinates for z if you were to graph this would be (8,0) and (-2,0)
So the square was fine, then the triangle decided to go for a hike.
now, if the triangle when it took off, it took 59 cm², and the square was left all by its lonesome with only 85 cm², that means with the triangle in it, the square is then 59 + 85 cm², or 144 cm².
Answer:
0.75:1

X² + 5x = -2x -12
Add 2x to each side.
x² + 7x = -12
Add 12 to each side.
x² + 7x + 12 = 0
Let's solve this quadratic by factoring.
We want two numbers that add to get 7 and multiply to make 12. These are 3 and 4.
Split the middle of the quadratic.
x² + 3x + 4x + 12 = 0
Factor the first two and last two terms.
(You should get the same thing inside the parentheses.)
x(x+3) + 4(x+3) = 0
(x+4)(x+3) = 0
Any value of x which causes either factor to equal 0 is a solution.
We can derive the following equations and solutions:
x+4 = 0 ⇒ x = -4
x+3 = 0 ⇒ x = -3
