Multiply : 4x ( 3x – 5y) ( x + 2y)
Answers
Answer:
ans
Step-by-step explanation:
Simplifying
4x(3x + -5y) = 0
(3x * 4x + -5y * 4x) = 0
Reorder the terms:
(-20xy + 12x2) = 0
(-20xy + 12x2) = 0
Solving
-20xy + 12x2 = 0
Solving for variable 'x'.
Factor out the Greatest Common Factor (GCF), '4x'.
4x(-5y + 3x) = 0
Ignore the factor 4.
Subproblem 1
Set the factor 'x' equal to zero and attempt to solve:
Simplifying
x = 0
Solving
x = 0
Move all terms containing x to the left, all other terms to the right.
Simplifying
x = 0
Subproblem 2
Set the factor '(-5y + 3x)' equal to zero and attempt to solve:
Simplifying
-5y + 3x = 0
Reorder the terms:
3x + -5y = 0
Solving
3x + -5y = 0
Move all terms containing x to the left, all other terms to the right.
Add '5y' to each side of the equation.
3x + -5y + 5y = 0 + 5y
Combine like terms: -5y + 5y = 0
3x + 0 = 0 + 5y
3x = 0 + 5y
Remove the zero:
3x = 5y
Divide each side by '3'.
x = 1.666666667y
Simplifying
x = 1.666666667y
Solution
x = {0, 1.666666667y}
