Factor the trinomial below. x^2 + 3x - 18

Hello from MrBillDoesMath!

(x -3) ( x + 6)

Discussion:

Initial observation:  

       6 * (-3) = -18 and 6 + (-3) = 3

The boldfaced values are the constant term and the coefficient of x. Hence the equation factors like this:

(x -3) ( x + 6)

Thank you,

you need more information to answer this question

step-by-step explanation:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
