Answer:

2(x^2+5)=60 to 2x^2+10=60

distributive property (a(b+c)=ab+ac)

2x^2+10=60 to 2x^2=50

property of equality or something like thht (a=a and b=b, so a-b=a-b) and also

 addative inverse (a+-a=0) (added -10 to both sides)

2x^2=50 to x^2=25

propery of euality and multiplicative inverse (a times 1/a=1) and one produce property (1 times a=a)

x^2=25 to x=+/-5

property of equality and something else

Step-by-step explanation:
