User: What is the solution set of x 2 + 5x + 1 = 0?

Weegy: input x^2+5 x+1 = 0 alternate form x (x+5)+1 = 0 4/21 (x+5/2)^2 = 1 (x+5/2)^2-21/4 = 0 solution x = 1/2 (-5-sqrt(21)) x = 1/2 (sqrt(21)-5)

User: What is the solution set of 7x 2 + 3x = 0?

Weegy: 7x + 4 + 3x -3

= 7x + 3x + 4 - 3

= 10x + 1

= 10x


User: What is the solution set of 7x 2 + 3x = 0?

Weegy: 7x + 4 + 3x -3

= 7x + 3x + 4 - 3

= 10x + 1

= 10x


User: What is the solution set of 7x 2 + 3x = 0?

Weegy: 7x + 4 + 3x -3

= 7x + 3x + 4 - 3

= 10x + 1

= 10x


User: What is the solution set of 7x2 + 3x = 0?

User: What is the solution set of 7x^2 + 3x = 0?

Weegy: 7x + 4 + 3x -3

= 7x + 3x + 4 - 3

= 10x + 1

= 10x


User: Score: What is the solution set of (3x - 1)2 = 5?

xfizzypotato|Points 30|

User: Which of the following constants can be added to x2 - 10x to form a perfect square trinomial?

Weegy: The answer is 1/4. Here, I'll show you how to get that answer: Trial and Error Method: 1) 1/4, [ 1/2 and 1 are the possible answers in the choices but we know that 1/2 is not a perfect square so it's not possible for 1/2 to be the answer. 2) Now try 1/4 and 1 and add them to the equation to get: x2 - x + 1/4 x2 - x + 1 3)Use the perfect square formula if you can: x2 - x + 1/4 becomes (x-1/2)2? Yes! x2 - x + 1 becomes (x-1)2 ...No! that's wrong because (a-b)2 = a2-2ab +b2 Thus, 1/4 is the answer. Easy Formula Method: 1) In a perfect square trinomial, c = (b/2a)2. a=1 because it's the co-efficient of x2 b=1 because it's the coefficient of x c=? and it's the missing constant using the formula and the given, c = 1/4. That's it! :D Good Luck! ]

User: y(y + 4)(y - 6) = 0 is a quadratic equation.

User: y(y + 4)(y - 6) = 0 is a quadratic equation. true or fals

Weegy: False. y(y 4) - y = 6 is written as: y^5 -y - 6 = 0. A quadratic equation is a second-order polynomial equation in a single variable y and this is not a second order polynomial equation.
befeeter|Points 406|

User: y(y + 4)(y - 6) = 0 is a quadratic equation.

User: Graph y -x2 + 1.

Weegy: x^2 has a negative coefficient so the parabola is opens downward. x-coordinate = 0/2(-1) = 0 ; since x-coordinate is in 0, then the graph crosses x-axis only 1.

User: What is the x-coordinate of the vertex of the parabola whose equation is y = 3x2 + 12x + 5?

Weegy: Derivative (tangent) is 6x + 9 equal to 0 at vertex (turning point) so x = -3/2.
