Answer:
a. 2(a -b + c)
b.= 4(4x³ -x -3)
Step-by-step explanation:
a. 2a +2b +2c -2a -2b -2c -2b +2c +2a
= 2a - 2a + 2a +2b - 2b -2b +2c - 2c + 2c
= 2a - 2b + 2c
= 2(a -b + c)
b. 12x³ -20x+58x³ -7x +1 -13 +31x -54x³
= 12x³ -20x +58x³ -7x + 1 -13 +31x -54x³
= 12x³ + 58x³ - 54x³ - 20x -7x +31x -12
= 16x³ -4x -12
= 4(4x³ -x -3)
