Question

Can someone help me with this problem?

Answer 1

Answer: I don't know





Step-by-step explanation: Jk, the answer is X = 3 or 1/3
/ = Fraction
^ = Power-of
* = Multiply
Move all the terms to the left then multiply the parentheses:
(5x+3) (10-2) - (7x) * (8x) = 0
(50x^2-10x+30x-6)-7x*88x
Then multiply variables:
(50x^2-10x+30x-6)-56x^=0
Now add all the numbers together:
6x^2+20x-6=0
= 256x
Use the following formula:
x1=−b−Δ√2a
x2=−b+Δ√2a
Set up the problem:
√ =√256=16
Part 1: -20-16/2x-6 = -36/-12 = 3
Part 2: -20+16/2x-6 = -4/-12 = 1/3
