If x is real can that of `x^2+3x+1` less than `(-5/4)`?

If x is a real number than x^(2)+x+1 is (a) less than (3)/(4) (b) zero for at least one value of x (c) always negative (d) greater than or equal to (3)/(4)

If x is real can the value of 3+2x-x^2 be greater than 4,

If x is real,then the value of x^(2)-6x+13 will not be less than

If (x+1)^(2) is greater than 5x-1& less than 7x-3 then the integral value of x is equal to (A)1(B)2(C)3(D)4

If the roots of the equation b x^2+""c x""+""a""=""0 be imaginary, then for all real values of x, the expression 3b^2x^2+""6b c x""+""2c^2 is (1) greater than -4ab (2) less than 4ab (3) greater than 4a b (4) less than - 4a b

If the roots of the equation b x^2+""c x""+""a""=""0 be imaginary, then for all real values of x, the expression 3b^2x^2+""6b c x""+""2c^2 is (1) greater than 4ab (2) less than 4ab (3) greater than 4a b (4) less than 4a b
