Answer: 24
Step-by-step explanation:
<u>Evaluate (y+z)2 when y=−3 and z=15.</u>
(-3 + 15)*2 = 12 * 2 = 24
Answer:
minus 15
Step-by-step explanation:
times the bottom by the right hand side
Answer:
the answer for this problem is x^2+2x-15
Step-by-step explanation:
(x+5)(x-3)
x(x-3)+5(x-3)
x^2-3x+5(x-3)
x^2-3x+5x-15
=x^2+2x-15
Answer:
min at (3, 0 )
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 = (x - 3)² = x² - 6x + 9 ← in standard form
with a = 1 and b = - 6 , then
= -
= 3
substitute x = 3 into the equation for corresponding value of y
y = (3 - 3)² = 0² = 0
vertex = (3, 0 )
• if a > 0 then vertex is minimum
• if a < 0 then vertex is maximum
here a = 1 > 0 then (3, 0 ) is a minimum
