20x^2-30=4x solve for x

ankoles [38]

Answer:

x=1.3288 or -1.1288

Step-by-step explanation:

Given $20x^{2}-30=4x$

Subtract 4x from both sides

$20x^{2}-4x-30=0$

Since we can factor out 2 from whole equation, let's factor out 2.

$2(10x^{2}-2x-15)=0$

Divide with 2 on both sides

$10x^{2}-2x-15=0$

We got the quadratic equation, we can solve for x using quadratic formula.

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

$x=\frac{2\pm\sqrt{2^{2}-4X10X(-15)} } {2X10}$

$x=\frac{2\pm\sqrt{604} }{20}$

$x=\frac{2\pm2\sqrt{151}}{20}$

$x=1.3288or-1.1288$

Alenkasestr [34]

Hey there!

“The quotient of -9 and y”

• Facts When you come across the word “QUOTIENT” in algebra/ math in general it usually MEANS you’re DIVIDING both your numbers by each other

• Guide: -9 will be your numerator and y would be your denominator (or -9 would be in your front whereas y will be in the back)

So, based on your guide we have your ANSWER should look like: “-9 ÷ y”

Good luck on your assignment and enjoy your day!
