Solve. 10x^2 = 6 + 9x10x 2 =6+9x10, x, start superscript, 2, end superscript, equals, 6, plus, 9, x Choose 1 answer: Choose 1 an
yulyashka [42]

Answer:

Option B.

Step-by-step explanation:

If a quadratic equation is defined as

ax^2+bx+c=0         .... (1)

then the quadratic formula is

x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}

The given equation is

10x^2=6+9x

It can rewritten as

10x^2-9x-6=0            .... (2)

On comparing (1) and (2) we get

a=10,b=-9,c=-6

Using quadratic formula we get

x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(10)(-6)}}{2(10)}

x=\dfrac{9\pm \sqrt{81+240}}{20}

x=\dfrac{9\pm \sqrt{321}}{20}

Therefore, the correct option is B.
