Answer:
X^2+6X-7=0
Step-by-step explanation:
To identify the quadratic equation use the following method
(X-a)(X-b)=0
Where
a=-7
b=1
(X+7)(X-1)=0
X^2+7X-X-7=0
X^2+6X-7=0
Answer:
x = 6
Step-by-step explanation:
5x + 15 = 45
Subtract 15 from both sides
5x = 30
Divide by 5 on both sides
x = 6
Hope this helps :)
Answer:
x= 
Step-by-step explanation:
We have given,

We need to solve for x.

Squaring both sides, we get:
3-5x = x + 2
or 3 - 2 = x + 5x
or 1 = 6x
or x = 
Hence we got x=
