What is the coefficient of the fourth term in the expansion of (x+5)^7 ?(i have 2 min please answer!)

step-by-step explanation:

infinity is the answer

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)
