Is it 2x +7= -3? If so the answer is -5
1)1,2,3,4,5,6
2)1/2
3)1/2
4)1/3
5)5 OR LESS THAN FIVE =1/6
ONLY LESS THAN FIVE (EXCLUDING FIVE)=4/6=2/3
the numbers are being divided by 4 so 12/4 =3
next number is 3
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
Solution is : <u>2p</u> .
