Which expression is not equivalent to −4x3+x2−6x+8?
Gekata [30.6K]

The expression which is not equivalent to the provided expression is expression number 1, x²(-4x+1)-2(3x-4).

<h3>What is the equivalent expression?</h3>

Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.

The expression given in the problem is

f(x)=-4x³+x²-6x+8

The option given as,

  • (1) x² (-4x+1)-2(3x-4)
  • (2) x(-4x²- x + 6) + 8
  • (3) -4x³ + (x - 2)(x - 4)
  • (4) -4(x³ - 2) + x(x - 6)

From the given expression, if we take out <em>x </em>from the first three terms, it looks like option 2.

f(x)=-4x³+x²-6x+8

f(x)=x(-4x²+x-6)+8

From the given expression, if the last three terms factored, it looks like option 3.

f(x)=-4x³+x²-6x+8

f(x)=-4x³+x^2-4x-2x+8

f(x)=-4x³+x(x-4)-2(x-4)

f(x)=-4x³+(x-4)(x-2)

Rearrange the given expression, and make it looks like option 4.

f(x)=-4x³+x²-6x+8

f(x)=-4x²+8+x²-6x

f(x)=-4(x³-2)+x(x-6)

Thus, the expression which is not equivalent to the provided expression is expression number 1, x²(-4x+1)-2(3x-4).

Simplify the expression using properties of exponents. 25a^-5b^-8/5a^4b
ivanzaharov [21]

Answer: The simplification is 5*a^{-9}*b^{-9}

Step-by-step explanation:

Here we need to use the property:

\frac{a^n}{a^m} = a^{n - m}

We have the expression:

\frac{25*a^{-5}*b^{-8}}{5*a^{4}*b}

We can separate it in parts with the same base, then we can rewrite this as:

\frac{25*a^{-5}*b^{-8}}{5*a^{4}*b} = \frac{25}{5} \frac{a^{-5}}{a^4} \frac{b^{-8}}{b}

Using the first property we can rewrite this as:

\frac{25}{5} \frac{a^{-5}}{a^4} \frac{b^{-8}}{b} = 5*a^{-5 - 4}*b^{-8 - 1} = 5*a^{-9}*b^{-9}
