Which polynomial represents the difference 6x2+3x-8 and x2-3x+4

Semmy [17]

The difference will be
$6x^2+3x-8 - (x^2-3x+4) \\ =
6x^2-3x-8-x^2+3x-4 \\ =
5x^2 -12$ .
Remember that parentheses are needed for the second polynomial because the negative is distributed to all of its terms.

A Triangle has an angle that measures 137.3 degrees. The other two angles are in a ratio of 3:4. What are the measures of those

Andreyy89

So we start off by subtracting 137.3 from 180 getting 42.5. If you add the ratios up (3+4) you get 7 and 7 should equal 42.5. thus,

42.5/7= 85/14

(85/14)*3=18.2 or (255/14 to be exact)
(85/14)*4= 24.29 or (170/7 to be exact)

I need help with multiplying polynomials using foil<br><br> Example <br> (X+5)(x-6)

MArishka [77]

Well (x+5)(×-6)
x*x =x2
x*-6=-6x
x*5 = 5x
5*-6= -30
add them all together to get x2-x-30.
I hope this is what you were asking
