5+7x-6x²
=-(6x²-7x-5)
=-(2x+1)(3x-5)
=(2x+1)(5-3x)

x²-(a+b)xy+aby²
=(x-ay)(x-by)

a³-5a²b+6ab²
=a(a²-5ab+6b²)
=a(a-2b)(a-3b)

6(2p-q)²-11(q-2p)+3
=[3(2p-q)-1][2(2p-q)-3]
=(6p-3q-1)(4p-2q-3)

(2x+1)(3x-5)
(x-ay)(x-by)
a(a-2b)(a-3b)
[2(2p-q)+3][3(2p-q)+1]

5+7x-6x^2
=-(6x^2+3x-10x-5)
=-[3x(2x+1)-5(2x+1)]
=-(2x+1)(3x-5)

x^2-(a+b)xy+aby^2
=x^2-axy-bxy+aby^2
=x*(x-ay)-by(x-ay)
=(x-ay)(x-by)

a^3-5a^2b+6ab^2
=a(a^2-5ab+6b^2)
=a(a^2-2ab-3ab+6b^2)
=a[a(a-2b)-3b(a-2b)]
=a(a-2b)(a-3b)

6(2p-q)^2-11(q-2p)+3
=6(2p-q)^2+11(2p-q)+3
=6(2p-q)^2+2(2p-q)+9(2p-q)+3
=2(2p-q)[3(2p-q)+1]+3[3(2p-q)+1]
=[2(2p-q)+3][3(2p-q)+1]
=(4p-2q+3)(6p-3q+1)

-(2x+1)(3x-5)
(x-y)(x-ay)
a(a-3b)(a-2b)
(4p-2q-3)(6p-3q-1)
