Step-by-step explanation:
the question means:
[(5k - 3h) x (8x + 10y + 12)] - [(7x - 4y) x (6h - k - 9)]
multiplying
= [(40xk + 50ky + 60k) + (-24hx - 30hy - 36h)]
- [(42hx - 7kx - 63x) + (24hy + 4yk + 36y)]
adding
= [40xk + 50ky + 60k - 24hx - 30hy - 36h]
- [42hx - 7kx - 63x + 24hy + 4yk + 36y]
simplifying subtraction using KFC rule (keep the minuend, flip the sign, change the subtrahend)
= 40xk + 50ky + 60k - 24hx - 30hy - 36h - 42hx + 7kx + 63x - 24hy - 4yk - 36y
add
= 47xk + 46ky + 60k - 66hx - 54hy - 36h + 63x - 36y
rearrange to form final answer
= -36h +60k +63x -36y -66hx +46ky +47xk
