x squared minus 4x equals 32.find the value of x plz.?

Answer 1

Just factor it. To do this, get 32 on the other side.

x^2 - 4x - 32 = 0

Now factor.

(x - 8)(x + 4) = 0

Use the Zero Product Property here.

x = 8 or x = -4

There's your answer. x can equal both 8 and -4.

Answer 2

the 1st is robust, you may combine like words. The x squared words are the comparable. the 2d is incorrect, x^3 and x^4 are unlike words and can't be mixed to x^7. the main simplified way is x^3 + x^4.

Answer 3

you have:
x^2 - 4x = 32

Change it to the form:
x^2 -4x -32 = 0

You can now use the quadratic equation.

Answer 4

if x=8.....8 squared = 64
4x=32

64-32=32

so X equals EIGHT
