Question

Find the zero of the polynomial 6x square - 3 - 7x

Answer 1

Answer:

=6xsquare-3-7x

=6xsquare-7x-3

=6xsquare-9x+2x-3

=(6xsquare+2x)-(9x+3)

=2x(3x+1)-3(3x+1)

=(3x+1)(2x-3)

=3x+1=0 or 2x-3=0

3x=-1 or 2x=3

X=-1/3 or x=3/2

Therefore zero's are -1/3 or 3/2

Answer 2

Answer:

-3/2  ,    -1/2

Step-by-step explanation:

6x^2-7x-3=0                 6x^2 into -3

6x^2+2x-9x-3=0                18x^2

2x common,-3common..     2x     -9x

2x(3x+1)-3(3x+1)=0

(2x-3)(3x+1)=0

the zeroes are

2x+3=0 => x=-3/2

3x+1=0 => x=-1/2
