4x2 + 28x + 49 = 4x2 + 14x + 14x + 49 = 2x(2x + 7) + 7(2x + 7) = (2x + 7)(2x + 7) or (2x + 7)2
Given 3x3 + 4x2 +x + 7 is divided by x2 + 1, find the results:
No, it has factors... 4x2 + 8x -21 = (2x+7)(2x-3)
49 Check when:- 4x2-28x+49 = 0 (2x-7)(2x-7) = 0 x = 7/2 and also x = 7/2
No - a quotient is the answer to a division sum, not the answer to an addition sum.
The given quadratic expression can not be factorized because its discriminant is less than zero.
The answer is: x = -5/2 and x = 7/2

-5 - 7 + 6 = -6
6 plus 7 plus 8 equals 6 plus 8 plus 7, what property is that?That is the associative property.
6.
-5 + -7 + 6 = -6
