Answer:

x= -1/3 or -2

Step-by-step explanation:

3x^2 +3x= -2x +2-4

3x^2 + 5x +2=0

by factorization method

3x(x+2) 1(x+2)=0

(3x+1)(x+2)

Answer:

x3(x+1)= –2(x-1)–4

3x^2+3x=–2x+2-4

3x^2+3x+2x=2-4

3x^2+5x=–2

3x^2+5x+2=0

3x^2+3x+2x+2=0

3x(x+1)2(x+1)=0

(3x+2)(x+1)=0

3x+2=0 or x+1=0

3x=–2 or x=–1

x=–2/3 or –1

Step-by-step explanation:

–remove brackets by multiplication

–form a quadratic equation

–and then solve either by means of quadratic formula or factorisation method
