8x3 = 24
10x2 = 20
therefore... 24 - 20 + 16x = 4 + 16x
================================
That's wonderful.
But A). He didn't say what the question is, and the answer above doesn't answer anything;
and B). What if the question means 8x3-10x2+16x ? What then ?
---------------------------------------------------------------------------------------------------
A) True. Vey true. You would need the value of X.
B) if that's the question then, to get the value of x you would need the rest of the equation (whatever it's equal to). Or if the problem is to simplify it then...
2x (4x2 + 5x + 8) ...
16x + 2 - 8 = 16x + 24 implies 16x - 6 = 16x + 24 subtracting 16x from both sides, this implies: -6 = 24 So the equation has no soultions.
8x2 + 16x + 8 = 0
The Commutative Property of Addition.
16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11
16X + 5
16x + 2 - 8 = 16x + 24 implies 16x - 6 = 16x + 24 subtracting 16x from both sides, this implies: -6 = 24 So the equation has no soultions.
8x2 + 16x + 8 = 0
The Commutative Property of Addition.
16x
16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11
16X + 5
Combining like terms, 16x + 20 = 180 or 16x = 160 so that x = 10
The given expressions can be simplified to: 16x-10
16x + 3
It is 75.
x2-16x+48 = (x-4)(x-12) when factored
15x2+16x-15 = (3x+5)(5x-3) when factored
