(7x + 4)(49x^2 - 28x + 16)
4x(4x^2 - 6x + 7)
(4x + 7)(16x2 - 28x + 49)
12x2 - 28x - 15= 12x2 - 18x - 10x - 15= 6x(2x - 3) - 5(2x - 3)= (6x - 5)(2x - 3)
9x2 - 28x + 20 = 9x2 - 18x - 10x + 20 = 9x(x - 2) - 10(x - 2) = (9x - 10)*(x - 2)
That depends on the - or + values of 28x and 980 which have not been given
49x2+28x+4 = (7x+2)(7x+2) when factored
The answer depends on the binomial.
(2x - 5) is a binomial factor
what is -12X squared +28X - 15? i figured it out myself. its (-6X + 5)(2X - 3).
The GCF is 28.
-8
4x(x - 7)
(7x + 4)(49x^2 - 28x + 16)
4x(4x^2 - 6x + 7)
There is one way to determine weather each binomial is a factor of X-4. The division of polynomials is what determines each binomial.
(4x + 7)(16x2 - 28x + 49)
