-2x2-12x-15
Final result :
-2x2 - 12x - 15
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((0 - 2x2) - 12x) - 15
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
-2x2 - 12x - 15 = -1 • (2x2 + 12x + 15)
Trying to factor by splitting the middle term
3.2 Factoring 2x2 + 12x + 15
15 x .30 = 4.50 discount 15-4.50= 10.50
10.50 x .40 = 4.20
Final cost of shirt 10.50-4.20 = $6.30
