Answer:
22x^2-9x+32
Step-by-step explanation:
(21x² - 6x +14) + (x²-3x+18)
To add, we need to combine like terms
21x^2+x^2 -6x-3x +14+18
22x^2-9x+32
The point of intersection of the two lines is at (1,-1)
<h3>System of equation</h3>
The given system of expression is shown below
x - 2y = 3
5x + 3y = 2
The solution to the system of equation is the point of intersection
From equation 1
x = 3 + 2y
Substitute into 2
5(3+2y) + 3y = 2
15 +10y + 3y = 2
13y = -13
y = -1
Substitute y = -1 into 3
x = 3 + 2y
x = 3+(-2)
x = 1
Hence the point of intersection of the two lines is at (1,-1)
