Question

X square -10 x - 1200 = 0. By mid term break solution question

Answer 1

Hi ,

x² - 10x - 1200 = 0

x² - 40x + 30x - 1200 = 0

x( x - 40 ) + 30( x - 40 ) = 0

( x - 40 ) ( x + 30 ) = 0

Now ,

x - 40 = 0 or x + 30 = 0

x = 40 or x = - 30

I hope this helps you

Answer 2

Heya !!!


X² - 10X -120 = 0




X² -40X +30X - 120 = 0




X ( X-40) +30 ( X-40) = 0



( X-40) ( X+30) = 0




( X-40) = 0 OR ( X+30) = 0



X = 40 OR X = -30.





HOPE IT WILL HELP YOU...... :-)
