(29) \\    \\  = 18 {x}^{2}   + 3x - 10 \\  \\  = 18 {x}^{2}    +15x   - 12x - 10 \\  \\  =3x(6x + 5) - 2(6x + 5) \\  \\  = (6x + 5)(3x - 2)

(30) \\  \\  = 2 {x}^{2}  + 11x - 21 \\  \\  = 2 {x}^{2}  + 14x - 3x - 21 \\  \\  =2x(x + 7) - 3(x + 7) \\  \\  = (x + 7)(2x - 3)

(31)   \\  \\  = 15 {x}^{2}  + 2x - 8 \\  \\  = 15 {x}^{2}  + 12x - 10x - 8 \\  \\  = 3x(5x + 4) - 2(5x + 4) \\  \\  = (5x + 4)(3x - 2)
