Question

twuce the square of the sum of a number and 3 is 98. find the number.​

Answer 1

Answer:

Let x be the missing number.

The equation is:

● 2(x+3)^2 = 98

Divide both sides by 2

●(2/2)×(x+3)^2 = 98/2

● (x+3)^2 = 49

● (x+3) = -√49 or (x+3) = √49

● (x+3) = -7 or (x+3) = 7

● x = -7–3 or x = 7–3

● x = -10 or x = 4

So x has two values.

x = {4, -10}
