Step-by-step explanation:
x(2x+5)=25____factorization method
2 {x}^{2} + 5x - 25 = 02x2+5x−25=0
2 {x}^{2} + 10x - 5x - 25 = 02x2+10x−5x−25=0
2x(x + 5) - 5(x + 5) = 02x(x+5)−5(x+5)=0
(x + 5)(2x - 5) = 0(x+5)(2x−5)=0
if (x+5)=0
x=-5
if (2x-5)=0
put -5 in equation
-5(2×(-5)+5) =25
-5(-10+5)=25
50+(-25)=25
25=25
