Answer:
product is a ⋅ c = 3 ⋅ − 6 = − 18 and whose sum is b = − 7 .
Step-by-step explanation:
Factor
− 7 out of − 7 x .
3 x 2 − 7 ( x ) − 6
Rewrite
−7 as 2 plus −9
3 x 2 + (2−9) x −6
Apply the distributive property.
3 x 2 + 2 x − 9 x − 6
The "charge" can be positive i.e carried by proton and negative i.e carried by electron, known as the physical property of matter, which experience force when placed in an electromagnetic field.
The basic characteristic of charge is that the like charges repel each other while opposite charge attract each other. The SI unit of charge is coulomb (C) and symbol to represent charge on any entity is "e". When the number of proton i.e "e+" is equals to number of electron i.e "e-" than a body is said to be neutral.
Answer:
The two real solutions are and
Step-by-step explanation:
The equation is a quadratic function of the form that can be solved by using the Quadratic Formula.
The plus and minus mean that the equation has two solution.
In order to identify is the equation has two real solutions we use the discriminant equation . Depending of the result we got:
1. If the discriminant is positive, we get two real solutions.
2. if the discriminant is negative, we get complex solutions.
3. If the discriminant is zero, we get just one solution.
Solution:
The equation has a=9, b=0, and c=-4
Using the discriminant equation to know if the quadratic equation has two real solutions:
The discriminant is positive which mean we get two real solutions.
Using the Quadratic Formula
then
and

Answer:
Step-by-step explanation:
When given the following function,
One is asked to find the roots. The roots of the equation are the zeros, where the graph of the equation intersects the (x) axis. To find these points on a quadratic equation (equation to the second degree -> the largest exponent in this equation is (2)), one should simplify the equation. Remember, during simplification, one is trying to get the equation of the parabola closets to the quadratic equation in standard form, this form is the following,
After simplifying the equation, one should use the quadratic formula to find the roots of the equation.
------------------------------------
Simplify, combine like terms, terms with the same variable to the same degree;
Now use the quadratic formula, the quadratic formula states the following,
Where the parameters (a), (b, and (c) represent the coefficients of the terms in the quadratic formula in standard form. Substitute in the respective coefficients in the given equation and solve for the roots,
Simplify,
