Answer 2

Answer:by using factrisation methodStep-by-step explanation:2x²+7x+52x²+5x+2x+5here see in statement, 2x and (5 means constant term). multiply 2x with 5 =10split the middle term into parts as when u multiple those two terms 10 come, when you add or sub those terms 7 come.here 5x×2=10and5+2=7then answer is 2x²+5x+2x+5take something common in 2x²+5xlet x is common x(2x+5)take something common in 2x+5nothing common in this statement,so write as it as and ur answer will be come x(2x+5)(2x+5)now write this answer like this (x)+(2x+5)hope helpful to you ☺️

both negative
