Hi,

(4x−2)(3x^2−2x+1)

=(4x+−2)(3x^2+−2x+1)

=(4x)(3x2)+(4x)(−2x)+(4x)(1)+(−2)(3x2)+(−2)(−2x)+(−2)(1)

=12x3−8x^2+4x−6x^2+4x−2

=12x3−14x2+8x−2

Have a great day!

option B) 3 pounds of beef is needed to make 6 times the recipe.

Step-by-step explanation:

step 1 :

Mitch used 14 pounds of beef = 34 liters of beef strogonoff

'x' pounds of beef = 1 liter of beef strogonoff

step 2 :

Rate = No. of pounds / No. of liters

(14 pounds / 34 liters) = (x pounds / 1 liter)

x = 14/34

x = 0.412

1 liter of beef strogonoff = 0.412 pounds of beef

step 3 :

To make 6 times the recipe = 6 $\times$ 0.412

= 2.5 pounds of beef ( approximately 3 pounds)

Tcecarenko [31]

For a monic quadratic (factor of 1 on $x^2$ ) we always add half the coefficient on the linear ( $x$ ) term, so

$\left(\dfrac 7 2\right)^2 = \dfrac{49}{4}$

Answer: 49/4

$x^2 + 7x + \dfrac{49}{4} = 4 + \dfrac{49}{4}$

$(x + \frac 7 2)^2 = 4 + \frac{49}{4}$
