4x2 plus 3=11
4x2+49x+90 = (4x+9)(x+10) when factored
dont know sorry
-((4x + 1)(x - 1))
There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -3.
2.
4x2 plus 3=11
It has 2 real solutions because the discriminant is greater than zero.
y=4x2+3x+8
Using the quadratic equation formula:- x = -0.5447270865 or x = 2.294727086
4x2+49x+90 = (4x+9)(x+10) when factored
4x2 - 30 = 34 ⇒ 4x2 = 64 ⇒ x2 = 16 ⇒ x = 4 or -4
4x2 = -12x, divide both sides by 4x: x = -3
10x2 - 64 = 36 + 6x2; whence, 4x2 - 100 = 0, x2 = 25, and x = ±5.
No.
