Answer:
Other solution of the equation is x = 5
Step-by-step explanation:
Given Quadratic Equation,
One of the solution of the given quadratic equation is x = -3
To find: 2nd solution of the equation.
We solve the given equation using middle term split method.
Consider,
x ( x - 5 ) + 3 ( x - 5 ) = 0
( x - 5 )( x + 3 ) = 0
x - 5 = 0 ⇒ x = 5
x + 3 = 0 ⇒ x = -3
Therefore, Other solution of the equation is x = 5

Answer:
The answer is
<h2>y + 2x = 2</h2>Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is 2x + y = 1
We must first write the equation in the general form above
That's
y = - 2x + 1
Comparing with the general equation above
Slope = - 2
Since the lines are parallel their slope are also the same
Slope of parallel line = - 2
So the equation of the line using point
( - 1 , 4) and slope - 2 is
<h3>We have the final answer as
<h3>y + 2x = 2</h3>Hope this helps you
