Solve. x^2+5=14?

Answer 1

x² = 9
x = ± 3

Answer 2

Simplifying
x^2 + 5 = 14

Reorder the terms:
5 + x^2 = 14

Solving
5 + x^2 = 14

Move all terms containing x to the left, all other terms to the right.

Add '-5' to each side of the equation.
5 + -5 + x^2 = 14 + -5

Combine like terms: 5 + -5 = 0
0 + x^2 = 14 + -5
x^2 = 14 + -5

Combine like terms: 14 + -5 = 9
x^2 = 9

Simplifying
x^2 = 9

Take the square root of each side:
x = {-3, 3}

Answer 3

Ok this is really not that hard if you break it down.

subtract 5 from each side of the equations.

so

x^2=9

Now you need to take the square root of each side of the equation

The sqaure root of x^2 is easy it is just x

for 9 think about what number times it self gives you 9 that would be
x=3, but you must also consider that when you multiply two negative numbers you get a positve number meaning that -3*-3 also =9 so you have two soultions to this problem being

x=3 and x= -3.

Answer 4

The strategy here (since there is no x, just x^2) is to isolate by subtraction the x^2 on the left and all numbers on the right.

This will give you x^2 = 9 so x must be either +3 or -3 sinc e either one squared will give you 9.

Answer 5

x² + 5 = 14
x² + 5 - 14 = 14 - 14
x² - 9 = 0
(x + 3)(x - 3) = 0
x + 3 = 0 or x - 3 = 0
x = -3 or x = 3
x = ±3, x є {-3,3}

Answer 6

x^2 - 9 = 0
(x-3)(x+3)=0

x=3 or -3

Answer 7

x= plus or minus 3

Answer 8

lol mate come on its just x = sqrt (9)
x= +3 or -3 .... donno why u need to ask this on here ....
have fun ^^
