 \huge \bold{hey \: there}

x²-2x-15=0

➡x²+3x-5x-15=0

➡x(x+3)-5(x+3)=0

➡(x+3)(x-5)=0

Hence, the zeroes are -3 and 5.

harsh4631: 12x2-5x-2=0. 12x2+3x-8x-2=0. 3x(4x+1)-2(4x+1)=0. ( 3x-2)(4x+1)=0. either x=2/3 or -1/4
mohammadumesuddin786: plzzz solve that all

x2-5x+3x-15=0

=x(x-5)+3(x-5)=0

=(x-5)(x+3)=0

either x=5 or x=-3
