x = - 3/2

Step-by-step explanation:

5(2x+3)^2=5

(2x + 3)^2 = 1

(2x + 3)^2 = 1^2. [1^2 = 1]

(2x +3) = 1

x = -3/2

Answer 2

Answer:

Hello...

Step-by-step explanation:

simplify by using (a+b)^2 = a^2+2ab+b^2 ,

use a=2 , b=3 according to question ,

5(4x^2+2*2*3+9)=5

5(4x^2+12+9)=5

5(4x^2+21)=5

20x^2+105=5

20x^2+105-5=0

20x^2+=0

through a^2-b^2=(a+b)(a-b) we get,

(20x)^2 - (10)^2

(20x+10)(20x-10)

Hope this helps you .....
