24x2 - 47x + 20 has roots of 4/3 and 5/8 ie factorises as (3x - 4)(8x - 5) Check: 24 x 16/9 - 47 x 4/3 = 42 and 2/3 - 62 and 2/3 = -20 and 24 x 25/64 - 47 x 5/8 = 9.375 - 29.375 = -20 QED
Yes, this is a polynomial (or quadratic) equation. X is the variable. So, for instance, if x=2, then the answer would be 96 + 68 + 12 = 176.
First, factor it out. This would first look like x(24x-29)=0, which would mean that x=0 or 29/24.
2x2 + 6 = 30 is your statement.2x2 = 24x2 = 12x = ±√12x = ±√(4*3)x = 2√3 or x = -2√3
3x(x - 5)(x - 3)
4x(4x^2 - 6x + 7)
x= 24x2 = 8

24x2
3x3 - 24x2 + 45x = 3x*(x2 - 8x + 15) = 3x*(x - 3)*(x - 5)
First, factor it out. This would first look like x(24x-29)=0, which would mean that x=0 or 29/24.
8x(1 - 3x)
2x2 + 6 = 30 is your statement.2x2 = 24x2 = 12x = ±√12x = ±√(4*3)x = 2√3 or x = -2√3
8(3x ^2 - 8)
the expression gfc of 8x is 24x2 and 48x3
The GCF is 24x2
