the answer: 20
$10x2/3
10x2 - 29x = 21 10x2 - 29x - 21 = 0 so x = -0.6 or x = 3.5
10x2-5x-5 = (10x+5)(x-1)
10x2 - 20xz + 15xy = 5x (2x - 4z + 3y)
10x2 - 56 = 88 - 6x2 : 10x2 + 6x2 = 88 + 56 : 16x2 = 144 : x2 = 9 : x = ± 3
That's not as problem, unless you're practicing the procedure to simplify fractions.(10x2 - 2x)/(4x) = (10x2)/(4x) - (2x)/(4x) = 2.5x - 0.5
10x2 + 101x + 10 = (10x + 1)(x + 10)
20
(10x + 3)(x - 1)
The answer is 21
4x3+10x2+2x+5= (2x+5)(2x2+1)
8x3 = 2410x2 = 20therefore... 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) ...
