Question

factorisation :
(ii) x (2x + 5) = 3.​

Answer 1

Answer:

$\huge{\underline{\red{\rm{AnswEr:}}}}$

x (2x + 5 ) = 3

$x(2x + 5) = 3 \\ 2 {x}^{2} + 5x = 3 \\ 2{x}^{2} + 5x - 3 = 0 \\ 2{x}^{2} + 2x + 3x - 3 = 0 \\ 2x(x + 1) + 3(x +1) = 0 \\ (2x + 3)(x + 1) = 0$

Answer 2

Answer:

X = –3

X = 1/5 or 0.5

Step-by-step explanation:

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

$2x {}^{2} + 6x - x - 3 = 0$

$2x(x + 3) - (x + 3) = 0$

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

$(2x - 1) = 0 \: or \: (x + 3) = 0$

x = 1/5 or x = –3

Hope it will help you.
