-(x - 1)(x2 + x + 1)
x2 - 14x = -49 ∴ x2 - 14x + 49 = 0 ∴ (x - 7)2 = 0 ∴ x = 7
(x + 8)(x + 2)
X4 - 144 (X2 - 12)(X2 + 12) As there is no linear term I see no further factoring.
x2 + 5x - 6 = x2 + 6x - x - 6 = x(x + 6) - 1(x + 6) = (x - 1)(x + 6)
(x+8)(x-4)
Trinomials are polynomials with three terms. ie. x2+2x+1
x2 + 5xy - 18y2 can not be factored.
(x + 9)(x - 1)
x2-64 = (x-8)(x+8)
There are no equations nor inequalities in the question only trinomial expressions. Expressions cannot be solved.
x2 - 14x + 49 = (x - 7)2
When the co-efficient of x2 is 1
-(x - 1)(x2 + x + 1)
x2 - 14x = -49 ∴ x2 - 14x + 49 = 0 ∴ (x - 7)2 = 0 ∴ x = 7
(x + 8)(x + 2)
X4 - 144 (X2 - 12)(X2 + 12) As there is no linear term I see no further factoring.
