The solutions for the expression (x + 2)² = 49 will be x = 5 and x = -9. The correct options are B and E.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given expression will be solved as below:-
(x + 2)² = 49
Remove the square from the left side of the equation and take the square root of the right side.
( x + 2 ) = √49
( x + 2 ) = ± 7
Take positive value and solve for x.
x + 2 = 7
x = 7 - 2
x = 5
Take the negative value and solve for x.
x + 2 = -7
x = -7 - 2
x =-9
Therefore, the solutions for the expression (x + 2)² = 49 will be x = 5 and x = -9. The correct options are B and E.
