This equation has two terms
Answer:
3x(3x + 2)
Step-by-step explanation:
4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer:
x= -1, y= 1
Step-by-step explanation:
2x + 6y = 4.........(1)
8x - 5y = 45........(2)
multiply equation (1) by 4
8x + 24y = 16......(3)
subtract equation (3) by (2)
29y = 29
y = 1
then substitute y=1 in equation (1)
2x + 6(1) = 4
solving for x
x = -2/2 = -1
Answer:
The last choice.
Step-by-step explanation:
The last term is - 20 and because we have a coefficient of 1 on the x^3, and in order to get this last term and the given roots the factors have to be
(x + 5)(x + 4)(x - 1) so it is the last option.
