Question

solve for x
fst plz classx​

Answer 1

Answer:

x = -7/2 or x = -3

Step-by-step explanation:

By splitting the middle term,

2x²+13x+21 = 0

=> 2x²+6x+7x+21 = 0

=> 2x(x+3)+7(x+3) = 0

=> (2x+7)(x+3) = 0

=> x = -7/2 or x = -3

Answer 2

2x^ + 6x+ 7x+ 21=0

2x(x+3) 7(x+3)=0

x=-3, x=-7/2

hope its helpful!
