3x2 - 16x + 5
= 3x2 - x - 15x + 5
= x(3x - 1) - 5(3x -1)
= (3x - 1)(x - 5)
or
I would use the quadratic equation. 3X^2 - 16X + 5 = 0
X = -b +/- sqrt(b^2-4ac)/2a
a = 3
b = -16
c = 5
X = -(-16) +/- sqrt[(-16)^2 - 4(3)(5)]/2(3)
X = 16 +/- sqrt(256 - 60)/6
X = 16 +/-sqrt(196)/6
X = (16 +/- 14)/6
X = 5
X = 1/3
check the easy one
3(5)^2 - 16(5) + 5 = 0
75 - 80 + 5 = 0
0 = 0
easy one checks; you try the 1/3 check

x2 + 16x - 348 cannot be factored. Solving for x with the quadratic formula results in x = -8 - 2√103 and x = -8 + 2√103
How do you solve an equation x squared plus 16x equals minus 44?
That won't factor neatly, so we apply the quadratic formula. x = -8 plus or minus 2 times the square root of 5 x = -3.5278640450004204 x = -12.47213595499958
How do you factor a polynomial of 4x plus 12x squared plus 16x cubed?
Re=Write as 16x^(3) + 12x^(2) + 4x Take out the common factor of '4' Hence 4(4x^(3) + 3x^)2) + x) Take out the common factor of 'x' Hence 4x( 4x^(2) + 3x + 1) The answer!!!!!
