Answer:
Step-by-step explanation:
6x^2+11x +4
Multiply the constant 4 by 6x^2.
Hence 4 times 6x^2 = 24x^2
Get two numbers when you multiply them it will give you 24 but if you add them it will give 11.
The numbers are +8 and +3 because +8 x +3= +24
and +8 + 3 = 11.
Substituting +8x +3x as 11x in the equation:
6x^2 +8x +3x +4
(6x^2+ 8x) + (3x + 4)
Factorizing the common things in the bracket.
2x(3x + 4) +1 (3x +4) since the common factor between (3x + 4) is 1.
Grouping the values outside together: (2x+1) (3x +4) =0
Therefore, 2x + 1 = 0 or 3x +4 = 0
2x = -1 or 3x = -4
x = -1/2 or -4/3.
Thanks.
