What is the vertex form of the equation y equals x squared plus 6x plus 2?

Y = X2 + 6X + 2set to 0X2 + 6X + 2 = 0X2 + 6X = - 2now, halve the linear coefficient ( 6 ), square it and add it to both sidesX2 + 6X + 9 = - 2 + 9gather terms on the right and factor the left(X + 3)2 = 7(X + 3)2 - 7 = 0==============vertex form(- 3, - 7)=======vertex


What is x squared plus 20x?

The only thing you can do is to rewrite it as x(x + 20). For anything else, you need the value of x.


How do you rewrite x2 plus 10x plus 25 in an equivalent factored form?

What is the vertex form of y equals x2 plus 4x - 7?

The vertex of the positive parabola turns at point (-2, -11)


In the vertex form of a quadratic function y equals a the quantity of x-b squared plus c what does the b tell you about the graph?

The standard form of the quadratic function in (x - b)2 + c, has a vertex of (b, c). Thus, b is the units shifted to the right of the y-axis, and c is the units shifted above the x-axis.


What is the vertex of x minus 4 squared equals to 2 y plus 5?

The equation you gave, 2y+5 = (x-4)2 can also be expressed as y = 0.5(x-4)2 - 5. In the form a(x-p)2 + q, the vertex is the point (p, q). Thus, the vertex of 2y + 5 = (x-4)2 is (4, -5).

What is the vertex of x2 plus 18x plus 19?

The vertex is (-9, -62).


What are the factors of the following polynomial k2 plus 18k plus 81?

To factor this, find two numbers whose product is 81 and sum 18. These two numbers are therefore 9 and 9. So we can rewrite the polynomial in its factored form as follows: (k+9)(k+9), or "k plus 9 squared"
