Solve x2 − 5x − 14 = 0

x=7,x=-2

Step-by-step explanation:

x^2-5x-14=0

x^2-7x+2x-14=0

x(x-7)+2(x-7)=0

(x-7)(x+2)=0

x=7;x=-2

= 7

= − 2

Step-by-step explanation:

hope this helps you sorry if it does not

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
