Question

F(x) = 3x² +5

g(x) = 4x - 2
h(x) = x²-3x+1
Find f(x) + g(x) - h(x).
O 2x² + 7x + 2
O 2x² + x + 2
O 5x² + 4
O 7x² + x +4

Answer 1

f(X)+g(X)-h(X)

3x²+5+4x+2-(x²-3x+1)

3x²+5+4x+2-x²+3x-1 [opened the brackets and changed the signs]

3x²-x²+4x+3x+5+2-1 [arranged the liked terms]

2x²+7x+7-1

2x²+7x+6

I don't see my answer in your options but trust me I have learned this and I am pretty sure that my answer is correct!!!!!!!
