Answer:
- x = 0 or 1
- x = ±i/4
- x = -5 (twice)
Step-by-step explanation:
Factoring is aided by having the equations in standard form. The first step in each case is to put the equations in that form. The zero product property tells you that a product is zero when a factor is zero. The solutions are the values of x that make the factors zero.
1. x^2 -x = 0
x(x -1) = 0 . . . . . x = 0 or 1
__
2. 16x^2 +1 = 0
This is the "difference of squares" ...
(4x)^2 - (i)^2 = 0
(4x -i)(4x +i) = 0 . . . . . x = -i/4 or i/4 (zeros are complex)
__
3. x^2 +10x +25 = 0
(x +5)(x +5) = 0 . . . . . x = -5 with multiplicity 2

Answer:
64
Step-by-step explanation:
*the sum of a triangle in degrees is 180*
44-72= 116
180-116= 64
Answer:
0.52
Step-by-step explanation:
(13/25)(4/4)=52/100
52/100=0.52
(6/13)/(6/12)= (6/13)*(12/6)= 12/13
This rule for division applies to all fraction divisions
