Answer:
(x-6)^2 =40
Step-by-step explanation:
The correct answer is (x-6)^2 =40
why??
Expand (x-6)^2
x^2 -12x+36 =40
Transpos 40 to the left side
So,
x^2 -12x+36 -40
Which is
x^2 -12x -4=0
It’s c because 3075/15=205, 3000/15 + 75/15 = 200+5, and 200+5=205 so 205=205 which is true. C is the answer
Answer:
f(x) = x² + 2x - 3
Step-by-step explanation:
From the graph the zeros are x = - 3 and x = 1
Thus the factors are (x + 3) and (x - 1) and
f(x) = (x + 3)(x - 1) ← distribute using FOIL
= x² - x + 3x - 3
= x² + 2x - 3
