Question

5x²+8x+3=0 by factorisation
​

Answer 1

$5x²+8x+3=0$

$5x^2-5x-3x+3=0$

$5x(x-1)-3(x-1)=0$

$(5x-3)(x-1)=0$

$Hence(5x-3) \: and (x-1) are \:the\:factors$

Answer 2

Answer:

5x^2 + 5x + 3x + 3 = 0

=> 5x(x+1) + 3(x+1) = 0

=> 5x + 3 = 0 ; x + 1 = 0

=> x = -3/5 ; x = -1

I hope it'll help you..
