Question

What is the answer Factorise: 2x² +7x+6.​

Answer 1

Answer:

11$x$+6

Step-by-step explanation:

2$x^{2}$= 4$x$ because 2 *2 = 4 + x = 4$x$

since 7$x$ is a like term we add it to 4$x$ and it becomes : 11$x$

Since 6 does not have a variable we do not add anything to it so, it stays the same and the simplified expression becomes : 11$x$ + 6

Answer 2

Answer:

2x  + 3 )(x   + 2 )

Step-by-step explanation:

2x² + 7x + 6          

Find two numbers multiplied together to get 6

and if you multiply one by 2, the answer is 7:

Tested:                                  

6 & 1  but 6 · 2 + 1 = 13 or 6 + 2 · 1  = 8 No

2 & 3  and 2 · 2 + 3 = 7    Yes

2x² = 2x  & x

 all signs are positive

   trinomial  factoring  (            )(            )

                                     (     +     )(      +    )

    2 and 3 are the numbers to use    (2x  + 3 )(x   + 2 )   or     (2x + 2) (x + 3)

The largest number goes with the 2x.

Therefore (2x  + 3 )(x   + 2 )

Check 2x(x + 2) + 3(x + 2)

              2x² + 4x + 3x + 6

              2x² + 7x + 6         checked
