solve the equation
 
 x square + 10 x -24=0

x+ 10x - 24 = 0
x2 + 12x - 2x -24 = 0
x(x-12) + 2(x - 12) = 0
(x + 2) (x - 12) = 0
therefore
x = - 2 and x = 12
hope you understood
thumbs up please

X2+10X-24=0
DISCRIMINANT
                             = b2-4ac
                              =102-4*1*-24
                            =100+96
                            =196
two solution.
x=-b​+/-root of b2-4ac/2a
=-10+/-root of 196/2
=-10+/-14/2
=-10+14/2 or -10-14/2
=4/2 or -24/2
=2 or-12.
value of x=2 or -12.
