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).

lbvjy [14]

Answer: \\  \frac{3 {x}^{2} - 4x - 15 }{ {x}^{2} - 9 }  \\  =  \frac{(3x + 5)(x  - 3)}{(x - 3)(x + 3)}  \\  =  \frac{3x + 5}{x + 3}
