Answer:
<h2>x = - 3/7 or x = 1</h2>
Step-by-step explanation:
7x² - 4x - 3 = 0
Rewrite - 4x as a difference
That's
7x² - 7x + 3x - 3 = 0
Factorize the expression
7x( x - 1) + 3 ( x - 1) = 0
(7x + 3)( x - 1 ) = 0
7x + 3 = 0 x - 1 = 0
7x = - 3 x = 1
x = -3/7
The solutions are
x = - 3/7 or x = 1
Hope this helps you
Answer:
undefined
Step-by-step explanation:
m= y/x
and x =0
Step-by-step explanation:
x={m,n,q,r}
Since, the set x contains 4 elements
Therefore,
n(x)=4
Again,
y={q,r,a,b}
Since, the set y contains 4 elements
Therefore,
n(y)=4
