The answer to x4+x3-14x2+4x+6 divided by x-3 is x3+4x2-2x-2
7+3w-13x
x3 + 13x2 + 42x = x(x2 + 13x + 42) = x(x2 + 6x + 7x + 42) = x[x(x + 6) + 7(x + 6)] = x(x + 7)(x + 6)
X3 + 13X2 + 40X factor out an X X(X2 + 13X + 40) factor the quadratic expression, what two factors of 40 add up to 13? X(X + 8)(X + 5) works the same if that is a negative in front of X3, just sign changes
x + 13x + 10x = 50 - 6
x(x - 13)(x - 1)
x(x - 1)(x - 13)
The answer to x4+x3-14x2+4x+6 divided by x-3 is x3+4x2-2x-2
x(x + 9)(x + 5)
14x2 + 15x + 4 = (7x + 4)(2x +1)
(2x+5)(7x-3)=14x2 +29x-15
7+3w-13x
x3 + 13x2 + 42x = x(x2 + 13x + 42) = x(x2 + 6x + 7x + 42) = x[x(x + 6) + 7(x + 6)] = x(x + 7)(x + 6)
X3 + 13X2 + 40X factor out an X X(X2 + 13X + 40) factor the quadratic expression, what two factors of 40 add up to 13? X(X + 8)(X + 5) works the same if that is a negative in front of X3, just sign changes
13x 32 plus 5x can be expressed mathematically as 173x/32.
x + 13x + 10x = 50 - 6
2x2+13x+15 = (2x+3)(x+5)
