  1. a, $x²-x-12$

    = $x²+3x-4x-12$

    = $x(x+3)-4(x+3)$

    = $(x-4)(x+3)$

    b, $4x²+5x-6$

    = $4x²+2x+3x-6$

    = $2x(2x+1)+3(x-2)$

    c, $5x²+14x-3$

    = $5x²+15x-x-3$

    = $5x(x+3)-(x+3)$

    = $(5x-1)(x+3)$

    d, $6x²+7x-3$

    = $6x²-2x+9x-3$

    = $2x(3x-1)+3(3x-1)$

    = $(2x+3)(3x-1)$

    e, $10x²-4x-6$

    = $10x²-10x+6x-6$

    = $10x(x-1)+6(x-1)$

    = $(10x+6)(x-1)$

    g, $-10x²+28x+6$

    = $-10x²+30x-2x+6$

    = $-10x(x-3)-2(x-3)$

    = $(-10x-2)(x-3)$
