Using the diamond, I get the factors 10/2 and 1/2. 2x^2+11x+5 factors to (2x+1)(x+5)=0
2x+1=0 2x=-1 x=-1/2
x+5=0 x=-5
Answer is D and E
2x+1=0 2x=-1 x=-1/2
x+5=0 x=-5
Answer is D and E
Answer:
Solution of the equation [tex]2x^2+11x+5=0[/tex] are:
D. x= -5
E. x= -1/2
Step-by-step explanation:
We are given a equation:
[tex]2x^2+11x+5=0[/tex]
Now, on solving the equation
[tex]2x^2+11x+5=2x^2+10x+x+5\\\\=2x(x+5)+1(x+5)\\\\=(2x+1)(x+5)[/tex]
Hence, (2x+1)(x+5)=0
⇒ either 2x+1=0 or x+5=0
⇒ either x= -1/2 or x= -5
Hence, solution of the equation [tex]2x^2+11x+5=0[/tex] are:
D. x= -5
E. x= -1/2
