Question

Write down at least five number pairs to solve the equation (r – 2)(s +1) = 0.

Answer 1

Answer:

$(r,s) => (2,-1);(2,0); (1,-1); (4,-1);(2,3)$

Step-by-step explanation:

Given

$(r - 2)(s +1) = 0$

Required

Write at least 5 pair of numbers

$(r - 2)(s +1) = 0$

This can be split to be

$r -2 = 0$  --- (1)

or

$s + 1 = 0$ --- (2)

Solve for r in (1)

$r = 2$

This means that for whatever value that s assumes, the equation will always be true when r = 2

Solve for s in (2)

$s = -1$

This means that for whatever value that r assumes, the equation will always be true when s = -1

So, we can make use of the following pair

$(r,s) => (2,-1);(2,0); (1,-1); (4,-1);(2,3)$
