Answer:
(2x+3)(x-1)
Step-by-step explanation:
x(2x+5)=3
=> 2x²+5x-3 = 0
=> 2x²+(3+2)x-3 = 0
=> x(2x+3)-1(2x+3) = 0
by taking comman "(2x+3)"
=> (2x+3)(x-1)

Question:
x(2x+5)=3
What to do?:
To factorise
Solution:
x(2x+5)=3
2x² + 5x -3 = 0
+5
-3/-2
2x² - 2x - 3x -3 = 0
2x ( x - 1 ) - 3 ( x + 3 ) = 0
( 2x - 3 ) ( x - 1 ) = 0
2x - 3 = 0
x = 3/2
x - 1 = 0
x = 1
Either x will be 3/2 or 1
