5(x+7)^2=245 find the steps

Mathematics
1 answer:
kakasveta [241]3 years ago
8 0

Answer:

0,-14

Step-by-step explanation:

5(x+7)²=245

divide both sides by 5

(x+7)²=49

Taking the square root of both sides

x+7=±7

Either x+7=7

subtract 7 from both sides

x+7-7=7-7

x=0

or

x+7=-7

subtract 7 from both sides

x+7-7=-7-7

x=-14
