Question

xsquare -8x-1280=0 solve the equation ​

Answer 1

Answer:

x = 40 or - 32

Step-by-step explanation:

x² - 8x - 1280 = 0

x² - 40x + 32x - 1280= 0

x(x - 40) + 32(x - 40) = 0

(x - 40) × (x + 32) = 0

Case 1

x - 40 = 0

x = 40

Case 2

x + 32 = 0

x = -32

So x = 40 or - 32.

Hope it helps.
