Answer

=5x²+12x-6

Step-by-step explanation:

you multiply -3x(x-4)-2x(x+3)

=-3x²+12x-2x²-6

group like terms

=-3x²-2x²+12x-6

=-5x²+12x-6

Answer:

x(x^2 + 6)

Step-by-step explanation:

We are to simplify -3x(x-4)-2x(x+3).  Begin by performing the indicated multiplication.  We get -3x^2 + 12x - 2x^2 - 6x.

Combining like terms, we get    -5x^2 + 6x, which is equivalent to

                                                       x(x^2 + 6)

The expression in scientific notation is given as follows:

3.5 x 10³.

<h3>What is scientific notation?</h3>

A number in scientific notation is given by:

a \times 10^b

With the base being a \in [1, 10).

For this problem, the expression is given by:

\frac{5 \times 10^2 \times 4.2 \times 10^4}{6 \times 10^3}

When two factors of a multiplication have the same base and different exponent, we <u>keep the base and add the exponents,</u> hence:

10^2 \times 10^4 = 10^6

5 x 4.2 = 21, hence the expression is:

\frac{5 \times 10^2 \times 4.2 \times 10^4}{6 \times 10^3} = \frac{21 \times 10^6}{6 \times 10^3}

When we divide two terms with the same base and different exponents, we keep the base and subtract the exponents, hence:

\frac{21 \times 10^6}{6 \times 10^3} = 3.5 \times 10^3

Which is the simplified expression.
