Question

Please help 5x^2+21x+4

Answer 1

(5x+1) (x+4)

Explanation:

Answer 2

I think it’s (x+4)*(5x+1)

Write 21x as a sum ~ 20x + x

5x^2+20x+x+4

Then you factor out the 5x from the expression

5x * (x+4) + x+4

Then you factor out x+4 from the expression

(X+4) * (5x+1)

Then that’s your answer :) have a great day
