Solve: x2 + 5x - 6= 0
A. -1, 6
B. 1, -6
C. -2, -3
D. 1,5

B

Step-by-step explanation:

Let's solve using factoring.

x²+5x-6=0

5 is the sum of the numbers, while -6 is their product.

Think: which two numbers add up to 5, but when multiplied, equal -6?

Those numbers are -1 and 6.

Now factor the polynomial:

(x-1)(x+6)=0

split into parts:

(x-1)=0

x-1=0

x=1

(x+6)=0

x+6=0

x=-6

So B

Hope this helps!

Since there are four ordered pairs in the given, there should be four points in the graph. These points should include, (-6,-4), (-4,-6), (3,-6), (5,0). Each ordered pair corresponds a single point in the graph. So, four ordered pair corresponds four points.
Answer. (B)
