Answer:
option B and option D
0 and 2
Step-by-step explanation:
Given in the question two functions
f(x) = x² - 4x + 3
g(x) = -x² + 3
f(x) = g(x)
x² - 4x + 3 = - x² + 3
Rearrange the like terms, x terms to the left and constant term to the right.
x²+ x² - 4x = 3 - 3
2x² - 4x = 0
Divide by two
2x²/2 - 4x/2 = 0/2
x² - 2x = 0
Take x as a common term
x(x-2) = 0
so
x = 0
or
(x-2) = 0
x = 2
i belive it is xy^2 but tell me if ou need more

Answer:
Step-by-step explanation:
hello :
5x²+8x-4 quadratic expression when : a = 5 and b=8 and c= -4
∆ = b²-4ac ∆ = 8²-4(5)(-4) = 64 +80 = 144 = 12²
X1 = ( -b -√∆)/2a X1 = (-8-12)/10 = -20/10= -2
X2 =(-b+√∆)/2a X2 = (-8+12)/10 = 4/10 = 2/5
us factorisation : a(X-X1)(X-X2)
5x²+8x-4= 5(x+2)(x-2/5) = (x+2)(5x-2)
you can verify ; (x+2)(5x-2) = 5x²-2x+10x-4 = 5x²+8x-4
