The length of a rectangle is represented by x, the width is represented by 6x^2-4x-2. What is the area of the rectangle?

navik [9.2K]

Answer:

$2x(3x^2-2x-1)$

Step-by-step explanation:

Area of a rectangle is simply length times width

{ $6x^2-4x-2$ } * x would be the area

That can be simplified to

$6x^3-4x^2-2x$

Which can be further simplified to

$2x(3x^2-2x-1)$

Need the help thanks guys

Answer:

x=−5+√29 or x=−5−√29

Step

Let's solve your equation step-by-step.

x2+10x+10=14

Step 1: Subtract 14 from both sides.

x2+10x+10−14=14−14

x2+10x−4=0

For this equation: a=1, b=10, c=-4

1x2+10x+−4=0

Step 2: Use quadratic formula with a=1, b=10, c=-4.

−b±√b2−4ac

−(10)±√(10)2−4(1)(−4)

2(1)

−10±√116

x=−5+√29 or x=−5−√29
