x2 - 21x = 72x2 - 21x - 72 = 0(x - 24) (x + 3) = 0x = 24x = -3
(7x+2)(2y-1)
It is: 3x*(x+7)
(5x-6)(x-3)
21x2 - 31x + 8 = (3x - 8)(7x - 1)
y = 3x + 21x2 = 3x(1 + 7x)
To factor 4x^2 - 21x + 5, we look for two binomials in the form (Ax + B)(Cx + D) that multiply to give 4x^2 - 21x + 5. We can determine the values of A, B, C, and D by examining the factors of 4 and 5. The factored form is then (4x - 1)(x - 5).
7(3x plus or minus 5) depending on the missing sign.
i hope you mean (2x^2 + 21x + 49) you cant solve it its already in its lowest possible form
10x2 + 21x - 10 = 10x2 + 25x - 4x - 10 = 5x(2x + 5) - 2(2x + 5) = (2x + 5)(5x -2)

x2 - 21x = 72x2 - 21x - 72 = 0(x - 24) (x + 3) = 0x = 24x = -3
2x2+21x+49 = (2x+7)(x+7)
x2 - 21x = 72x2 - 21x - 72 = 0(x - 24) (x + 3) = 0x = 24x = -3
21x + 9 = 180 21x = 180 - 9 21x = 171 x = 171/21 x = 8.143
