Question

Write a system of linear equations with -3,9 as its solution

Answer 1

Let the variable of the equation be x.

Solution of the equation is given to us, hence,

x = -3 and x = 9

x + 3 = 0 and x - 9 = 0

Multiplying,

(x + 3)(x - 9) = x² - 9x + 3x - 27 = x² - 6x - 27

Hence, the linear equation with solution -3 and 9 is x² - 6x - 27.
