Answer:
Yes, twice
Step-by-step explanation:
The equation will intersect the x-axis when y = 0, so we have
x² - 4x = -3 now solve this quadratic for x...
x² - 4x + 3 = 0
factor...
(x - 3)(x - 1) = 0,
so at x = 1 and x = 3, the function crosses the x-axis
See the graph below

Answer:
-1.1, 6.1
Step-by-step explanation:
-2X^2+10X+14=0
(-2X^2+10X+14)/-2=0
X^2-5X-7=0
Then use the quadratic formula because you can't factor
Fill in the equations and solve. One should have the plus and the other should have the minus and that's how you get the 2 different answers.
A=1
B=-5
C=-7
