<h2> </h2><h2>b. \: 2 {x}^{2}  - 5x</h2><h2> </h2><h2>c. \: 6 {x}^{2}  + 8x</h2><h3> </h3><h3>d. \: 6 {x}^{2}  - 12x</h3>

solution,

a. \: x(x + 2) \\  \:  \:  = x \times x + 2 \times x \\  \:  \:  =  {x}^{2}  + 2x

b . \: x(2x - 5) \\  \:  = x \times 2x - x \times 5 \\  \:  \:  = 2 {x}^{2}  - 5x

c. \: 2x(3x + 4) \\  \:  = 2x \times 3x + 2x \times 4 \\  \:  \:  = 6 {x}^{2}  + 8x

d. \: 6x(x - 2) \\  \:  \:  = 6x \times x  - 6x \times 2 \\  \:  \:  = 6 {x}^{2}  - 12x

What is the solution of -(x + 1) - 5 &gt; 10
Pie
<span> -(x + 1) - 5 > 10
 -x - 1 - 5 > 10
 - x - 6 > 10
Add 6 to the both sides, 
-x - 6 + 6 > 10 + 6
-x > 16
x < -16  [ changed sign 'cause changed -sign ]

In short, Your Answer would be x < -16

Hope this helps!</span>
