Answer:
and
Step-by-step explanation:
Consider given system ,
We have to solve for and
In matrix form,
then this is in form of AX = b,
A=
X=
b=
Pre-multiply by both side, we get,
..............(1)
First finding inverse of A ,
Thus, inverse of A is ,
Now substitute in (1) , we get,
Multiply , we get,
Thus, and
Answer:
2x^4 - 9x^3 -8x^2 + 15x
Step-by-step explanation:
(x^2-5x)(2x^2+x-3) distribute first
2x^4
x^2 + x = x^3
5 * 2x^2 x= 10x^3
5x^1+1 = 5x^2
5 * 3x = 15x Put them all together
2x^4 + x^3 - 3x^2 - 10x^3 - 5x^2 + 15x Like terms
2x^4 + x^3 -10x^3 - 3x^2- 5x^2 + 15x Add similar terms
= 2x^4 + x^3 - 10x^3 - 8x^2 + 15x more adding terms
2x^4 - 9x^3 -8x^2 + 15x
Hope my answer has helped you, if not i'm sorry.
< that I think maybe be the answer hope that's help
Answer:
5x - 1 or x>−1
Step-by-step explanation:
Just combine like terms: 13,-14
Combine like terms: 6,10
Divide by -4:-4x/-4<4/-4
