PLEASE HELP
A quadratic equation is shown:

x2 − 8x + 13 = 0

Which of the following is the first correct step to write the above equation in the form (x − p)2 = q, where p and q are integers?

A) x2 − 8x + 13 − 5 = 0 − 5
B) x2 − 8x + 13 − 3 = 0 − 3
C) x2 − 8x + 13 + 5 = 0 + 5
D) x2 − 8x + 13 + 3 = 0 + 3

Add 3 to both sides, so you will have

x^2 - 8x + 13 + 3 = 3

x^2 -8x + 16 = 3

And now the left side is a perfect square trinolmial: (x-4)^2.

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)
