Answer:
Step-by-step explanation:
x2 = 36?
solution
x^2-(36)=0
Factoring: x2-36
Check : 36 is the square of 6
Check : x2 is the square of x1
Factorization is : (x + 6) • (x - 6)
(x + 6) • (x - 6) = 0
x+6 = 0
x = -6
x-6 = 0
add 6 to both side
x = 6
x = -6
The solutions of an equation are the true values of the equation.
The expression that represents the solution(s) of [tex]\mathbf{x^2 = 36}[/tex] is [tex]\mathbf{x = \pm6}[/tex]
The equation is given as:
[tex]\mathbf{x^2 = 36}[/tex]
Take square roots of both sides
[tex]\mathbf{x = \pm\sqrt{36}}[/tex]
Express the square root of 36 as 6.
So, we have
[tex]\mathbf{x = \pm6}[/tex]
So, the expression that represents the solution(s) of [tex]\mathbf{x^2 = 36}[/tex] is [tex]\mathbf{x = \pm6}[/tex]
