X^2 + 4x + 8 = 0
( x + 2 ) ( x + 2 ) = 0
i am a mathematics teacher. if anything to ask please pm me
Y = 1
Using y = mx + c.
Compare to y = 1, y = 0x + 1 ,
We can see that the slope m = 0 and the vertical intercept, c = 1.
For the line perpendicular to y = 1
Condition for perpendicularity m₁m₂ = -1
m₁ = 0, m₂ = ?
0*m₂ = -1
m₂ = -1/0 = Negative Infinite or Infinite
Slope of line perpendicular to y = 1, is = Infinite.
The number = 7
(2x-5)4=36
2x-5=9 <----- divide by 4
2x=14 <----- add 5
x=7 <----- divide by 2
We are given the following expression and want to expand it and simplify it.
Use the FOIL method for expanding
Simplify
Let me know if you have any questions or need clarifications, thanks!
