Question

8. The zeroes of the polynomial x²-3x - 4 are​

Answer 1

Answer:

zeroes are 4,-1

Step-by-step explanation:

x²-3x-4

x²-4x+x-4

x(x-4) +1(x-4)

(x-4) (x+1) = 0

x-4 = 0 , x +1 = 0

x = 4 , x = -1

x = 4,-1

Answer 2

Answer:

x²-3x - 4 =0

x²-4x + 1x -4 =0

x(x-4) + 1(x -4)=0

(x+1) (x-4)= 0

=) x +1 =0 , x-4 =0

x = -1 , x = 4

so, x = -1, 4

so, The zeroes of the polynomial x²-3x - 4 are -1 and 4
