Answer:
x=1.5y
Step-by-step explanation:
4(x/y+1)=10
x/y+1=10/4
x/y+1=2.5
x/y=2.5-1
x/y=1.5
x=1.5y
Answer:
-3x⁴ - 9x³ + 15x² = -3x² (x² + 3x -5)
10x³ -35x² + 6x - 21 = (2x - 7) (5x² + 3)
Step-by-step explanation:
-3x⁴ - 9x³ + 15x² = -3x² (x² + 3x -5)
10x³ -35x² + 6x - 21 = (2x - 7) (5x² + 3)
I assume the way it's written is like this
4x^2 - 8x + 4 - (2x^2 - 3x + 7)
If that's the case, just combine like terms.
Let's begin with 4x^2. It has the same components as the -2x^2 (remember, since it's being subtracted in the original equation, the number is negative.)
4x^2 - 2x^2 = 2x^2
Now -8x and 3x (be careful, sometimes there's a minus sign in and out of the parentheses, this makes the number positive again
-8x + 3x = -5x
And then 4 and -7
4 - 7 = -3
So the simplified version is finally:
2x^2 - 5x - 3
Hope this helped! If you need me to explain anything, don't be afraid to ask.
