Add the x's squared together to get 2x^2+x. You cannot add anymore so the answer is 2x^2+x
x=9 squared
You can't because it is not a quadratic equation.
(x-3)(x-2)
x^(2) - 10x + 16 = 0 Factors of '16', which are, 1,2,4,8,16. Select two numbers from this list that add/subtract to '10' . They are '2' and '8'. Setting up brackets ( x 2)(x 8) Since '16' is positive(+), then both signs must be the same. Since '10x' is negative (-) , then both signs are negative. Hence (x - 2)(x - 8 ) = 0 When x - 2 = 0 x = 2 & when x - 8 = 0 x = 8 So the two answers are ,2, & ,8, .
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
(x - 3)(x + 5)
X=1
Use the quadratic formula. x = -4.265564 or -0.234436
(3x-2)(x-2)
x2 + 6x + 8 = 0 Solve for x.X = -2 or X = -4
You have to put your heart into it!
f(x) = x2 + 5x + 1 The roots of this equation are x = -0.2087 and x = -4.7913 (approx).
