Solution

15(5x-4)²-10(5x-4) Final result : 5 • (5x - 4) • (15x - 14)
Step by step solution : Step1: Equation at the end of step1: (15 • ((5x - 4)²)) - 10 • (5x - 4) Step2: Equation at the end of step2: 15 • (5x - 4)² - 10 • (5x - 4) Step3: Pulling out like terms :
3.1 Pull out 5x-4 After pulling out, we are left with : (5x-4)• (15 (5x-4)+(10 (-1)))
Step4: Pulling out like terms :
4.1 Pull out like factors: 75x - 70=5•(15x - 14)
Final result : 5 • (5x - 4) • (15x - 14)
