Answer:
See Graph
Step-by-step explanation:
Find the Solution for
1x2+3x−4=0
using the Quadratic Formula where
a = 1, b = 3, and c = -4
x=−b±sqrtb^2−4ac/2a
x=−3±sqrt3^2−4(1)(−4/2(1)
x=−3±sqrt9−−16/2
x=−3±sqrt25/2
Simplify the Radical:
x=−3±sqrt5/2
We get x=22x=−82
which becomes
x=1
x=−4
Here is the graph:

The given expression :
For coordinates:
put x = 0 then :
Coordinate : (x, y) = (0, 1)
Put x= 1 and simplify :
Coordinate : (x, y) = ( 1, 0.5)
Put x = (-2) and simplify :
Coordinate : (x, y) = ( -2, 4)
Put x = (-3) and simplify :
Coordinate : (x, y) = (-3, 8)
Substitute x = (-1) and simplify :
Coordinate : (x, y) = ( -1, 2)
So, the coordinates are :
The graph is :
Answer:
The answer is "".
Step-by-step explanation:
Therefore in this question the "bh" were the multiplied and these values includes the variable which is solving by the isolating of "b".
Let's Divides the both sides for h.
