Question

Find the natural value of x square from the equation x square + 12 x is equal to 64

Answer 1

Answer:

Please give me 5 star with brilliant

Step-by-step explanation:

Given, x² + 12x = 64

⇒ x² + 12x - 64 = 0

⇒ x² + 16x - 4x 64 = 0

⇒ x(x + 16) - 4(x+16) = 0

⇒ (x+16)(x-4) = 0

⇒x= -16,4

As x > 0, then x = 4

Answer 2

Step-by-step explanation:

$x^{2} +12x-64=0\\x^{2} +16x-4x-64=0\\x(x+16)-4(x+16)=0\\(x-4)(x+16)=0$

Therefore, x = 4 or -16.

Hope this helps you!!
