2x-2y=-4
Multiply eq.by 3
6x-6y=-12
-3x-3y=0
Multiply eq.by 2
-6x-6y=0
from both new eq.
6x-6y=-12
-6x-6y=0
So adding both eq. We get
-12y=-12
So y=1
From eq.1
2x-2y=-4
2x-2(1)=-4
2x-2=-4
2x=-4+2
2x=-2
x=-1
so x=-1 and y=1

The zero of the polynomial 6x power 2 + 19 X - 77 is​
Iteru [2.4K]

Answer:

The zeros of the polynomial are x = 7 or x = -11/2

Step-by-step explanation:

The zeros of a polynomial refers to the solution of the polynomial.

6x^2 + 19x -77

6x^2-14x+ 33x -77

2x(x-7) + 11(x-7)

= (2x + 11)(x-7)

2x + 11 = 0

x-7 = 0

2x = -11

x = -11/2 = -5.5

and x-7 = 0

x = 7

So the zeros of the polynomial are x = 7 or x = -11/2
