Answer:
Explanation:
Factorize the expressions:
a. 5x²+15x+10
→we see all coefficients are divisible by 5 so we factor by 5
5(x²+3x+2)
→ what numbers have the sum 3 and product 2 ? ...1 and 2 so we can factor
5(x+1)(x+2)
c. 4x²-6x-4
→we see all coefficients are divisible by 2 so we factor by 2
2(2x²-3x-2)
Cannot be further factored.
e. 2x²-7x-15
Cannot be factored.
