False
(5x - 1)(x + 6)
= 5x2+70-16+9x-2 = 5x2+9x+52 = 5x2+9x1+52 This implies coefficient of degree 1 is 9. Ans.
9. And the word is minus, not minis.
(5x-6)(x-3)
5x2+500 = 844.45 5x2 = 844.45-500 5x2 = 344.45 x2 = 344.45/5 x2 = 68.89 x = the square root of 68.89 = 8.3 x = 8.3
The GCF is 5x2
(5x + 2)(x + 1)
18 because, 5x2=10 10+8=18! Your welcome. It's not a problem at all. I love math!
5x2-16x+12 = (5x-6)(x-2) when factored
(5x - 1)(x + 6)
True.
x3 + 5x2 - x - 5 = (x2 - 1)(x + 5) = (x + 1)(x - 1)(x + 5)
Yes. If you add, subtract or multiply (but not if you divide) any two polynomials, you will get a polynomial.
5x2 + 3x - 1 does not have rational factors.
= 5x2+70-16+9x-2 = 5x2+9x+52 = 5x2+9x1+52 This implies coefficient of degree 1 is 9. Ans.
I am assuming this is: .2x4 - 5x2 - 7x, which would be a Quartic Polynomial.
5x2 - 16x + 12 = 5x2 - 10x - 6x +12 = 5x(x - 2) - 6(x - 2) = (x - 2)(5x - 6) Whether or not these are in descending order depends on the value of x.
