Question

-2x^2 + 4x - 8
I need the possible x intercepts or solutions

amistre64 · Answer

have you tried the quadratic formula?

apoorvk · Answer

x intercept is value of the x when y is 0.

so equate the equation to zero and find the x values for it.

try quadratic formula if you cannot factorise it.
