$\huge \bold{hey \: there}$

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.

mohammadumesuddin786: 12x2-5x-2=0

mohammadumesuddin786: x2-15x+56=0

mohammadumesuddin786: x2+9x+18=0

mohammadumesuddin786: x2+6x+9=0

mohammadumesuddin786: x2-1=0

mohammadumesuddin786: x2+19x+78=0

mohammadumesuddin786: x2+28x+192=0

mohammadumesuddin786: find the all zero of the polynomials

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

Answered by harsh4631

x2-5x+3x-15=0

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

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

either x=5 or x=-3
