Solve Quadratic Equations by Factoring:

mr_godi [17]

Answer:

x = 0 or 1
x = ±i/4
x = -5 (twice)

Step-by-step explanation:

Factoring is aided by having the equations in standard form. The first step in each case is to put the equations in that form. The zero product property tells you that a product is zero when a factor is zero. The solutions are the values of x that make the factors zero.

1. x^2 -x = 0

x(x -1) = 0 . . . . . x = 0 or 1

2. 16x^2 +1 = 0

This is the "difference of squares" ...

(4x)^2 - (i)^2 = 0

(4x -i)(4x +i) = 0 . . . . . x = -i/4 or i/4 (zeros are complex)

3. x^2 +10x +25 = 0

(x +5)(x +5) = 0 . . . . . x = -5 with multiplicity 2

Jack cuts four squares with side length X inches from corners by a 5" x 7" cardboard rectangle. He folds the remaining cardboard

viktelen [127]

Answer:

$V = x^3-24x^2+35x$

Step-by-step explanation:

Jack makes a cuboid. If the length is l, the width is w and the height is h, then its volume is

$V = lwh$

The height is determined by the side of the square cut out of each corner.

$h = x$

Along the length of the width, the length of two sides of the square are cut.

$l = 7 - 2x$

$w = 5 - 2x$

$V = lwh = (7-2x)(5-2x)(x)$

$V = x(35-24x+4x^2) = x(x^2-24x+35) = x^3-24x^2+35x$

Given: 7x/2 < 5. Choose the solution set.

Aleksandr [31]

we need to move the 5 to the left side in order to be left with zero:
 $(7x/2)-5\ \textless \ 0$
Rewrite/simplify the equation:
 $\frac{7x-(5*2)}{2}= \frac{7x-10}{2}$
Simplify:
$\frac{7x-10}{2} \ \textless \ 0$
Evaluate/Solve the equation :
 $\frac{7x-10}{2}=0*2
 \\ 7x-10=0
 \\ 7x-10=-10
 \\ 7x=-10
 \\ \frac{7x}{7}= \frac{-10}{7} 
 \\ x= \frac{-10}{7}$
