Answer:
x = -1/2, 7
Step-by-step explanation:
2x^2 = 13x + 7
bring everything to one side: 2x^2 - 13x - 7 = 0
factor it out: 2x1 = 2 and -7x1 = -7.
-7x2 = -14 and 1x1 = 1
-14 + 1 = -13, so these numbers work
you end up with (2x + 1)(x - 7) = 0
<u>solve each section:</u>
2x + 1 = 0 x - 7 = 0
2x = -1 x = 7
x = -1/2
Answer:
q(x) = (x²-8x+64) and remainder r(x) is 0
Step-by-step explanation:
I assume that the polynomial P(x) is
P(x) = x3 + 2x2 -16x +640
d(x) = x+10
The long division:
<u> x2 - 8x + 64 </u>
x+10)x3 + 2x2 - 16x +640
<u> -(x3 + 10x2)</u>
-8x2 - 16x
<u> -(-8x2 - 80x)</u>
64x +640
-(<u>64x +640)</u>
0
hence, q(x) = (x²-8x+64) and remainder r(x) is 0

Option B is the correct answer
Hi,
Out of given expressions you have those would be correct:
64 - 8 - 4
and this one if in brackets...
64 - (8 + 4)
Hope this helps.
