Correct simplification of the given expression =
Step-by-step explanation:
Given the expression :
The following steps required for the multiplication of polynomials are:
Distribute each terms of the first polynomial to every term of the second polynomial. Apply these steps to the given expressions;
when you multiply two terms together you must multiply the coefficient (numbers) and add the exponent.
⇒
Combine like terms;
Therefore, the correct simplification of the given expression is,
If you would like to solve (2x - 6) * (3x^2 - 3x - 6), you can do this using the following steps: (2x - 6) * (3x^2 - 3x - 6<span>) = 2x * 3x^2 - 2x * 3x - 2x * 6 - 6 * 3x^2 + 6 * 3x + 6 * 6 = 6x^3 - 6x^2 - 12x - 18x^2 + 18x + 36 = 6x^3 - 24x^2 + 6x + 36 </span> The correct result would be <span>6x^3 - 24x^2 + 6x + 36.</span>

Simplify the left side. 0.02x+(40-0.1x)=0.42x -0.08x+40=0.42 since 0.42x contains the variable to solve for, move it to the left side of the equation by subtracting 0.42x from both sides -0.08x+40-.0.42x=0 -0.5x=-40 x=80
