C.
Step-by-step explanation:
x^2+3x-5x+15
x^2-2x+15
??? thats it simplified? im not sure honestly
Answer:
x = 2 and y = 3
Step-by-step explanation:
We have
x+2y = 8 -----equation (i)
2x-y = 1 -----equation (ii)
Now,
x+2y = 8
or, x = 8-2y ------equation (iii)
Again,
2x-y = 1
or, 2x = 1+y
or, 2x-1 = y
Putting the value of 'x' from equation (iii)
or, 2(8-2y)-1 = y
or, 16-4y-1 = y
or, 16-1 = y+4y
or, 15 = 5y
or, y = 15/5
or, y = 3
Putting the value of 'y' in equation (iii)
x = 8-2y
or, x = 8-(2×3)
or, x = 8-6
or, x = 2
Therefore, x = 2 and y = 3.
Prime polynomial cannot be factorized into the product of two polynomials of lesser degree. Example: x2+x+1. Good luck.
Answer:
Step-by-step explanation:
1) Separate terms with roots from terms without roots.
2) Simplify 4 + 1 to 5.
3) Invert and multiply.
4) Simplify to 25.
5) Subtract 4 from both sides.
6) Simplify 25 - 1 to 24.
7) Take the square root of both sides.
