Answer:
5x^2 -6x +1
Step-by-step explanation:
(3х^2 – 2) + (2х^2 – бх + 3).
Combine like terms
(3х^2 + 2х^2 – бх + 3-2)
5x^2 -6x +1
The number which could be added to both sides of the equation to complete the square is; -2.25.
<h3>Which number could be added to both sides of this quadratic equation to complete the square?</h3>
The quadratic equations give in the task content is; 1=x²-3x. Hence, to express the equation by completing the square method; we have;
1 - 2.25 = (x -3/2)² - 2.25
Hence, the number which should be added to both sides of the equation is; -2.25.

Remember the rules of PEMDAS
1. First you want to evaluate the parentheses. (4-1) = 3
2. Square:
3^2 = 9
3. Multiply: 9*2 = 18
Your answer is C
2 + 65 + 7 × 3
= 2 + 65 + 21
= 67 + 21
= 88
answer is 88
