Answer:
answer is down below
Step-by-step explanation:
2x^2 + 5x + 2 =0
multiply 2x^2 x 2 = 4x^2
find two numbers that multiply together to get 4 and add together to make 5
so 4 and 1.
Put them in back in the equation: 2x^2 + x + 4x + 2
split it up in the middle and factorise
so 2x^2 + x becomes x(2x+1)
and 4x+2 becomes 2(2x+1)
<u>so (x+2)(2x+1) is the answer</u>
