( 2x + 7) ( 3x - 7) + ( x + 4)(x - 8)
= [ 2x ( 3x - 7) + 7(3x - 7)] + [ x(x - 8) + 4(x - 8)]
= 6x^2 - 14x + 21x - 49 + x^2 - 8x + 4x - 28
= ( 6x^2 + x^2) + ( 21x - 14x - 8x + 4x) + ( - 49 - 28)
= 7x^2 + 3x - 77
= [ 2x ( 3x - 7) + 7(3x - 7)] + [ x(x - 8) + 4(x - 8)]
= 6x^2 - 14x + 21x - 49 + x^2 - 8x + 4x - 28
= ( 6x^2 + x^2) + ( 21x - 14x - 8x + 4x) + ( - 49 - 28)
= 7x^2 + 3x - 77
