Question

Please HELP me on my ASSESSMENT practice its URGENT Find the ZEROS of each quadratic function by factoring

Answer 1

13.

`x^2+x-20=(x+5)(x-4)`

Then, the zeros are x=-5 and x=4.

14.

`x^2-4x-60=(x+6)(x-10)`

Then, the zeros are x=-6 and x=10.

15.

`x^2-15x+50=(x-5)(x-10)`

Then the zeros are x=5 and x=10.

16.

`x^2-x-72=(x+8)(x-7)`

Then the zeros are x=-8 and x=7.

17.

`x^2+2x-48=(x+8)(x-6)`

Then the zeros are x=-8 and x=6.

18.

`x^2-12x+36=(x-6)^2`

Then there is only one zero at x=6.

19.

`x^2+32x+60=(x+30)(x+2)`

Then the zeros are x=-30 and x=-2.

20.

`x^2-21x-100=(x+4)(x-25)`

Then the zeros are x=-4 and x=25.
