Question

Simplify −4(−y v)-4(5v−y)

Answer 1

Expand the brackets. two negatives multiplied together make a positive and a positive and a negative multiplies together make a negative. so you would times everything in the first bracket by -4 and everything in the second bracket by -4 also because it also has a -4 outside the bracket:
 4y-4v-20v+4y
