First let's multiply the first equation by -5 and the second one by 3
And now let's add these two new equations.
We found y's value. Let's put it in one of the equations to find x.
<span>Solution : (-4, -1)
Good Luck !

Answer:
(2, 5 )
Step-by-step explanation:
Given a quadratic in standard form : y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= -
y = 3x² - 12x + 17 ← is in standard form
with a = 3 and b = - 12, thus
= -
= 2
Substitute x = 2 into the function for corresponding value of y
y = 3(2)² - 12(2) + 17 = 12 - 24 + 17 = 5
vertex = (2, 5 )
