Solve ( x - 2)( x + 7) =0
lara31 [8.8K]

Answer:

x = 2 or

x = -7

Step-by-step explanation:

(x - 2)(x + 7) = 0

x - 2 = 0

Add 2 to both sides

x - 2 + 2 = 2 + 0

x = 2

OR

x + 7 = 0

Subtract 7 from both sides

x + 7 - 7 = 0-7

x = -7

Therefore

x = 2 or

x = -7

Plzz help me to find coefficient in binomial theorem (25 points)
Viefleur [7K]

<em>Denote x2 by y. </em>

<em>  </em>

<em>(x2-3)7=(y-3)7 </em>

<em>  </em>

<em>This is a binomial expansion in y, and you want the coefficient of y4 because y4=x8 </em>

<em>  </em>

<em>You have 7 terms of (y-3) in (y-3)7.  To get the fourth power of y, you need to choose y from four of the terms.  The number of ways you can do this is the combinations of 7 things taken 4 at a time.  This is: </em>

<em>  </em>

<em>7!/(4!3!)=35</em>

<em />

<em>So, the coefficient of x8 in the given expansion will be 210.</em>

<em>HOPE IT HELPS</em>

<em>THANK YOU </em>
