-(2x+12) (9x^2+4x-9) please show all work!

Mathematics

Answer:

108 - 30x - 116x² - 18x³

Step-by-step explanation:

We have to get the value of - (2x + 12) (9x² + 4x - 9)

Now, using the distributive property of multiplication we get

- (2x + 12) (9x² + 4x - 9)

= -[2x (9x² + 4x - 9) + 12 (9x² + 4x - 9)]

= -[(18x³ + 8x² - 18x) + (108x² + 48x - 108)]

= -[18x³ + 116x² + 30x - 108]

= 108 - 30x - 116x² - 18x³ (Answer)

What is the negative root of 2x^2 + x − 6 = 0
max2010maxim [7]
Hello! 

Here we can use the quad formula to solve for the x values or roots.
x=(-2+or - \sqrt{2^2-4*2*-6})/2*2 = -2 and 3/2
The negative root for this equation is x=-2

We find the roots of an equation by solving for x by different ways, most common ones being the quadratic formula of x= [-b +/-sqrt(b^2-4ac)]/2a or factoring and setting equal to zero and solving for x value(s) that way. Also the roots are where the graph of the equation crosses the x-axis.



Hope this helps. Any questions please just ask. Thank you kindly
