Answer: m² + 3m - 10 = 0
Step-by-step explanation:
From the expression, considering
6x + 5 = m
The original expression
( 6x + 5 )² - 10 = -18 - 15
Factorize the right hand expression,
-18 - 15 = -3( 6x - 15 )
Since m = 6x + 5 , we now substitute for m in that expression
m² - 10 = -3m
Now re arrange the equation in the form,
ax² - bx + c = 0
Now back to the equation,
m² + 3m - 10 = 0,
So the equivalent equation will be
m² + 3m - 10 = 0
1-d
2-c
3-e
4-b
5-a
It's very simple. Try..
These are vertical angles and they are equal
3x + 50 = 6x - 10
50 + 10 = 6x - 3x
60 = 3x
60/3 = x
20 = x <==
