We can first factor all the terms by 2:
<span>6x^2 - 10x - 4=2(3x^2-5x-2)
</span>
Then we solve 3x^2-5x-2=0.
Discriminant : 25+4*3*2=49=7^2 hence the roots are (5-7)/6 and (5+7)/6 which are -1/3 and 2
Hence 3x^2-5x-2=(x-2)(3x+1)
Thus 6x^2-10x-4=2(x-2)(3x+1)
Answer:
choice 1) x = 4
Step-by-step explanation:
∠2 = ∠6
4x+44 = 6x+36
reduce:
2x = 8
x = 4
Answer:
Two
Explanation:
The solution of a system of equations is defined as the values which satisfies both equations.
Graphically, the solutions are represented by the points of intersection between the two equtaions.
In the given graph, we have a circle and a line, we can note that these two intersect in two points.
This means that the system has two solutions
Hope this helps :)
When you multiply the equation out and you simplify like terms you get.
2x^2 + 6xy + 4y^2
