Answer:  19=18 | This is the answer | False

Step-by-step explanation:

Okay, so to solve this problem we need to see if the equations equal each other on both sides. For example 1+3=7-3 , in this problem we do the math on both sides to get the answer. 1+3=4 and 7-3 =4, so it will be 4=4 which is true. so for your problem you just need to do the math on both sides. and when you do that you get 19=18, this is false or untrue as they clearly don't mathematically.

Thanks for using brainly!

Solve the quadratic equation using the quadratic formula: 3x^2 - 6x = 5
Fantom [35]

Answer:

x_{1} = 1+\frac{2\sqrt{6}}{3} \\\\x_{2} = 1-\frac{2\sqrt{6}}{3}

Step-by-step explanation:

3x^2 - 6x - 5=0

quadratic formula:

x=\frac{-b+-\sqrt{b^{2}-4*a*c}}{2*a}

a=3     b=-6     c=-5

x=\frac{-(-6)+-\sqrt{(-6)^{2}-4*3*-5}}{2*3}

x=\frac{6+-\sqrt{36+60}}{6} \\\\x=\frac{6+-\sqrt{96}}{6} \\\\x=\frac{6+-\sqrt{2^{2}*2^{2}*2*3 }}{6} \\\\x=\frac{6+-4\sqrt{6}}{6} \\

so we have:

x_{1} = 1+\frac{2\sqrt{6}}{3} \\\\x_{2} = 1-\frac{2\sqrt{6}}{3}

Factor quadratic equation 6x.squared +41x + 63 = 0
vlabodo [156]

Answer:

x1= -9/2 ; x2= -7/3

Step-by-step explanation:

Rewrite to 6x^2 + 27x +14x +63 = 0

Factor and get 3x(2x + 9) + 7(2x + 9) = 0

Factor again and get (2x + 9)(3x + 7) = 0

Separate into possible cases -> 2x + 9 = 0; 3x + 7 = 0

The equation has two solutions: x1 = -9/2 and x2 = -7/3

Hope this helped!!
