Question

Solve the equation by factoring! 2x^2 + 5x + 2 = 0

Answer 1

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)

so (x+2)(2x+1) is the answer
