-6 = 3 x -2
13 = 5 x 3 - 2
→ 5x² + 13x - 6 = (5x - 2)(x + 3)
(x + 3)(3x - 2)
(3y - 5)(y + 5)
(7a - 1)(6a + 1)
(3r - 2)(3r - 2) or (3r - 2) squared.
it is (x-y)(x-y) :)
There are no rational factors.
There is no rational factorisation.
(3y - 5)(y + 5)
(a - 2)(a^2 + 6)
(b-c)(a+b)-ac
(x + 3)(3x - 2)
(7a - 1)(6a + 1)
(3r - 2)(3r - 2) or (3r - 2) squared.
it is (x-y)(x-y) :)
6(b - ac + b2 - bc)
6(ab - ac + b2 - bc)
Factor out -2: -2(x squared +11x-20). This is fully factored.
