Vertex The vertex is easily determined by completing the square. y = 3(x^2 + 4x + p) + 15 p = (b/2)^2 p = (4/2)^2 p = 4 y = 3(x^2 + 4x + 4 - 4) + 15 y = 3(x^2 + 4x + 4) - 4(3) + 15 y = 3(x + 2)^2 - 12 + 15 y = 3(x + 2)^2 + 3 In vertex form, y = a(x - p)^2 + q, the vertex is located at the point (p, q) Therefore, the vertex is at (-2, 3) ~~~~~ Intercepts: y intercept: y = 3(0)^2 + 12(0) + 5 y ...

How do you write the polynomial 3x^2-8x- 12x^5- 5x3+ 2x^4- 6 …
-12x^5+2x^4-5x^3+3x^2-8x-6 I am assuming the 3 in the -5x term should be an exponent. 3x^2-8x-12x^5-5x^3+2x^4-6 To write the polynomial in standard form, write it in order of decreasing exponents. I have highlighted the exponents in red. -12x^color(red)5+2x^color(red)4-5x^color(red)3+3x^color(red)2-8x-6 Note that the 8x term has an exponent of color(red)1 …
How do you solve x^2-12x+5=0 by completing the square?
2018年1月15日 · just add and subtract so we have x^2 - 12x + 5 = 0 x^2 - 12x + 36 - 36 + 5 = 0 (x+6)^2 -31 = 0 therefore x + 6 = +-31^(1/2) so x = +-31^(1/2) - 6 hope u find it helpful :)

How do you convert the following equation from standard to
2016年11月15日 · Please see the explanation. The given equation is the equation of a parabola that opens upward (or downward). The vertex form of the equation of a parabola that opens upward (or downward) is: y = a(x - h)^2 + k where (h, k) is the vertex and "a" is the coefficient of the x^2 term. Given: y = 3x^2 + 12x + 5 a = 3, therefore, add 0 in the form 3h^2 - 3h^2 to the …
How do you factor 12x^2+19x+5? - Socratic
2015年5月2日 · We can Split the Middle Term of this expression to factorise it In this technique, if we have to factorise an expression like ax^2 + bx + c, we need to think of 2 numbers such that: N_1*N_2 = a*c = 12*5 = 60 AND N_1 +N_2 = b = 19 After trying out a few numbers we get N_1 = 15 and N_2 =4 15*4 = 60, and 15+4= 19 12x^2+19x+5 = 12x^2 + 15x +4x + 5 = 3x(4x + 5) + …
How do you factor completely: 12x^5 + 6x^3 + 8x^2? | Socratic
2015年7月14日 · 12x^5+6x^3+8x^2 = 2x^2(6x^3+3x+4) = 12x^2(x-x_1)(x-x_2)(x-x_3) where x_1, x_2, x_3 are defined below. 12x^5+6x^3+8x^2 = 2x^2(6x^3+3x+4) Let f(x) = 6x^3+3x+4. This is way too messy to solve, but for the record... Use Cardano's method to solve f(x) = 0. Let x = u + v f(x) = 6(u+v)^3 + 3(u+v) + 4 =6u^3+6v^3+(18uv+3)(u+v) + 4 Let v = -1/6u. Then 18uv+3 = 0 …
