5x^2 - 5 = -17
First add 5 to both sides:
5x^2 = -12
Now, divide by 5
x^2 = -12/5
Take the square root of both sides
x = sqrt -12/5
Because there can't be a square root of a negative number, your answer is:
x = sqrt -12/5 * i
Hope this helps!
When you factor out -1, you get ...
... -(2 4/5 - 6/7)
Answer:
3x²(4x-3)
Step by step explanation:
Factorise 12x³-9x²
first, find the HCF of the terms.
the HCF is 3x²
Then you can use the HCF to multiply all terms, each divided by the HCF.
3x²(12x³/3x²-9x²/3x²)
Dividing, we'll have
3x²(4x-3)
2/3 * x +13 = 22
2/3x + 13 = 22
if u need to solve it then ....
=> 2/3x = 22 - 13
=> 2/3x = 9
=> 2x = 9*3 = 27
=> x = 27/2
Hope it helps !!!
