How do you factor 3x squared minus 16x plus 5?
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

Simplify the variable expression which is 16x- 8-5-6x-4?
To simplify the expression 16x - 8 - 5 - 6x - 4, first combine like terms. Combine the x terms by subtracting 6x from 16x to get 10x. Then, combine the constants by adding -8, -5, and -4 to get -17. Therefore, the simplified expression is 10x - 17.

How do you factor the polynomial expression 3xx plus 16x plus 5?
NOTE: xx can be written as x^2 i.e. x squared 3x^2 + 16x + 5 = 3 x^2 + x + 15x + 5 (Since 16x = x + 15x) = x ( 3x + 1 ) + 5 ( 3x + 1 ) = ( x + 5 ) ( 3x + 1 ) Therefore the factors are ( x + 5 ) and ( 3x + 1 )
