2. B = {x, y) 3. C = {1, 2, 8} 4. D = { a, b, c, d] 5. E = {a​

yes, whats the problem?

answer: our required factorization will be

(3x+4)(x²-5)

step-by-step explanation:

since we have given that

now, we will write it as :

so, we get

5(3x+4)

similarly,

here, we get,

2(3x+4)

together it becomes,

hence, our required factorization will be

(3x+4)(x²-5)

answer: 5a, -3a
