Given,

-3x^2+2x+4=-x-3-3x^2+3x+7=0

Solving the above equation,

x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}

Here, a=-3, b=3 and c=7

Therefore,

x=\frac{-3\pm\sqrt[]{9+84}}{-6}x=\frac{-3+\sqrt[]{93}}{-6}\text{ or }x=\frac{-3-\sqrt[]{93}}{-6}\text{ }

Therefore,

x=-1.11\text{ or }x=2.11

What is the product?<br><br> (6 r minus 1)(negative 8 r minus 3)
just olya [345]

Answer:

The required product is -48r^2-10r+3

Step-by-step explanation:

Consider the provided expression.

(6r-1)(-8r-3)

Open the parentheses.

6r\left(-8r\right)+6r\left(-3\right)+\left(-1\right)\left(-8r\right)+\left(-1\right)\left(-3\right)

-6\cdot \:8rr-6\cdot \:3r+1\cdot \:8r+1\cdot \:3

-48r^2-18r+8r+3

Add the like terms.

-48r^2-10r+3

Hence, the required product is -48r^2-10r+3
