Explicación paso aSolution for (2a-3b)(4a^2+6ab+9b^2)= equation:
Simplifying
(2a + -3b)(4a2 + 6ab + 9b2) = 0
Reorder the terms:
(2a + -3b)(6ab + 4a2 + 9b2) = 0
Multiply (2a + -3b) * (6ab + 4a2 + 9b2)
(2a * (6ab + 4a2 + 9b2) + -3b * (6ab + 4a2 + 9b2)) = 0
((6ab * 2a + 4a2 * 2a + 9b2 * 2a) + -3b * (6ab + 4a2 + 9b2)) = 0
Reorder the terms:
((18ab2 + 12a2b + 8a3) + -3b * (6ab + 4a2 + 9b2)) = 0
((18ab2 + 12a2b + 8a3) + -3b * (6ab + 4a2 + 9b2)) = 0
(18ab2 + 12a2b + 8a3 + (6ab * -3b + 4a2 * -3b + 9b2 * -3b)) = 0
(18ab2 + 12a2b + 8a3 + (-18ab2 + -12a2b + -27b3)) = 0
Reorder the terms:
(18ab2 + -18ab2 + 12a2b + -12a2b + 8a3 + -27b3) = 0
Combine like terms: 18ab2 + -18ab2 = 0
(0 + 12a2b + -12a2b + 8a3 + -27b3) = 0
(12a2b + -12a2b + 8a3 + -27b3) = 0
Combine like terms: 12a2b + -12a2b = 0
(0 + 8a3 + -27b3) = 0
(8a3 + -27b3) = 0
Solving
8a3 + -27b3 = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '27b3' to each side of the equation.
8a3 + -27b3 + 27b3 = 0 + 27b3
Combine like terms: -27b3 + 27b3 = 0
8a3 + 0 = 0 + 27b3
8a3 = 0 + 27b3
Remove the zero:
8a3 = 27b3
Divide each side by '8'.
a3 = 3.375b3
Simplifying
a3 = 3.375b3
Combine like terms: 3.375b3 + -3.375b3 = 0.000
a3 + -3.375b3 = 0.000
