12*2=24
24*3=72
72*4=288
288*5=1440
7x^2-3x - (3x^2 +4x -5) multiply negative one across the entire second term
7x^2 - 3x -3x^2 -4x +5
4x^2 -7x +5
The answer would be 80 because you are multiplying each number by 2. You multiply 5 x 2 = 10, 10 x 2 = 20, 20 x 2 = 40, and then 40 x 2 = 80. That is how I got the answer 80!!
