<h2>quadratic equation</h2>

the solution of the quadratic equation is twofold, to find the solution, you can factor it first.

4x² + 8x + 3 = 0

4x² + 6x + 2x + 3 = 0

2x(2x + 3) + 1(2x + 3) = 0

(2x + 3) (2x+1) = 0

2x+3=0 or 2x+1=0

x=-3/2 x=-1/2

<em><u>You can try to prove that the x value above will produce 0</u></em>

• first x = -3/2

= 4(-3/2)² + 8(-3/2) + 3

= 9 - 12 + 3

= 0 (true ✔️)

• second x = -1/2

= 4(-1/2)² + 8(-1/2) + 3

= 1 - 4 + 3

= 0 (true ✔️)

Suppose a triangle has two sides of length 3 and 4 and that the angle
rodikova [14]

Answer:

B

Step-by-step explanation:

We can use the law of cosinse:

c^{2} = a^{2} + b^{2} − 2ab cos(C)

Suppose the two sides are a and b, and the angle betweent them is C.

c^{2} = 3^{2} + 4^{2} − 2*3*4 cos(60)

We can simplify this to get c^{2} =25-12=13

c=\sqrt{13}

Answer choice B
