Go on to photo math it's good for equations
combining like terms in a polynomial is adding or subtracting together terms that have the same degree in the exponents.
example. 3x^3 + 5x^6 + 2x^3 +7x + 9x^6
= 7x + 5x^3 + 14x^6
X is 15because 15-10=5
x= 3*5
x=15
Answer:
The first option
Step-by-step explaination:
1.
a= 1 , b= -2 , c= -1
x=1
now use the x value to find y
y = -2
vertex (1,-2)
