(2x-3)(5x+2)= 2x(5x+2)-3(5x+2)= 10x^2+4x-15x-6=10x^2-11x-6
(3x-7)(4x-1)= 3x(4x-1)-7(4x-1)= 12x^2-3x-28x+7= 12x^2-31x+7
10x^2-11x-6+12x^2-31x+7= 10x^2+12x^2-11x-31x-6+7= 22x^2-42x+1
Therefore, (2x-3)(5x+2)+(3x-7)(4x-1)= 22x^2-42x+1
(3x-7)(4x-1)= 3x(4x-1)-7(4x-1)= 12x^2-3x-28x+7= 12x^2-31x+7
10x^2-11x-6+12x^2-31x+7= 10x^2+12x^2-11x-31x-6+7= 22x^2-42x+1
Therefore, (2x-3)(5x+2)+(3x-7)(4x-1)= 22x^2-42x+1
