Answer:
Step-by-step explanation:
2+7x+3
by splliting middle term
2+6x+1x+3
by taking 2x common from 2+3x and 1 from 1x +3
we will get,
2x(x+3)+1(x+3)
taking x+3 common
we get the answer
(2x+1)(x+3)
and if 2+6x+1x+3=0
ten value of x=-1/3 and -3
MARK ME AS BRAINLIEST
Step-by-step explanation:
using the a -b Methoding
the factors of 2×3=6
which sum to + 7 are + 6 and + 1
split the middle term using these factors
2x2 +6x+x + 3
factor by grouping
2x(x + 3) +1 (x+ 3)
Take out the common factor ( x + 3)
( x + 3) ( 2x+ 1)
2x2 +7x+ 3 = (x + 3) ( 2x+1)
Hope it is helpful pls follow me I will follow u back
plsss mark as brain list answer
Thank you
