Answer:
(x+1)(x-1)(x+3)(x-3)
Step-by-step explanation:
x4-10x^2+9
Group expression so that the coefficients of the x^2 terms add up to +9.
= x^4 -9x^2 - x^2+9
match coefficients in both groups
= x^4 -9x^2 - (x^2-9)
factor each group
= x^2 (x^2-9) - 1(x^2-9)
now factor out the common factor (x^2-9)
= (x^2-1)(x^2-9)
Finally, factor each quadratic factor
= (x+1)(x-1)(x+3)(x-3)
Answer:
The answer to your question is Area = 6 u²
Step-by-step explanation:
Process
To find the area of the picture divide the figure between a square and a right triangle, determine the area of each figure and finally add them up.
1.- Calculate the area of the square
Area = side x side
= 2 x 2
= 4 u²
2.- Calculate the area of the triangle
Area = base x height / 2
base = 2 height = 2
Area = 2 x 2 /2
Area = 2 u₂
3.- Total area
Area = 4 + 2
= 6 u²

Answer:
x = 34
Step-by-step explanation:
4x - 10 + x + 20 = 180
5x + 10 = 180
5x = 170
x = 34
