The derivative of 2x2 + 4x + 8 is 4x+4.
If: 4x+(-12) = 8 then 4x = 20 and x = 5
x=5
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
x=3
I'm going to assume the polynomial in question is 2x7+(3-2x3)+(5x8-4x) Expanding out the polynomial: 2x7+3-2x3+5x8-4x Order the terms by powers of x: 5x8+2x7-2x3-4x+3 Since 8 is the highest power of x, the degree of the polynomial is 8.
The derivative of 2x2 + 4x + 8 is 4x+4.
4x + 8 + 7x + 12 = 11x + 20
4x+8
If: 4x+(-12) = 8 then 4x = 20 and x = 5
8 + y = 4x8 + y - 4x = 4x - 4x 8 + y - 4x = 0 8 - 4x + y = 0
-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3
4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x
5x + 3 - 4 + 4x = 9x -1
If the equation is y = 4x + 8, then the standard form is 4x - y + 8 = 0
9x + 8 = 4x + 23Subtract 8 from both sides9x = 4x + 15Subtract 4x from both sides5x = 15Divide both sides by 5x = 3
3x-8
