college algebra
11x - 3 ≥ -4x^2 4x^2 + 11x - 3 > 0 (x+3)(4x-1) ≥ 0 critical values are x = -3 and x = 1/4 and y = 4x^2 + 11x - 3 is a parabola opening upwards, with intercepts -3 and 1/4 ..... so x ≤ - 3 OR x ≥ 1/4

college algebra, Please help!!
check your typing. Were you asking ... is x-2 a factor of f(x) .... ? f(2) = 4(2^4) - 7(2^3) - 5(2) + 2 = 64 - 56 - 10 + 2 = 0 yes, x-2 is a factor.

From the given zeros, factors would be (x+6) , (x-6-i) and (x-6 + i) the complex factors simplify to x^2 -12x +37 (complex numbers always appear in conjugate pair form) but that would only produce a cubic, so there has to be multiplicity of the above zeros. two options : f(x...

by the way you can see from the graph that 2 is a double root If you were clever enough to factor this you would have (2x-1)(x-2)(x-2)(x-7)
