Answer:
5
Step-by-step explanation:
Im asuming you meant " x = 2 ".
According to PEMDAS, parenthese come first so...
10 - ( 2 + 3 )
= 10 - 5
= 5
Answer:
-1
Step-by-step explanation:
you find where the line crosses the y-intercept
E. 5x^2 - 10= 0; 5(x^2 - 2)= 0; x^2= 2; x = √2
f. x^2 - x=0; x(x -1)= 0; x = 0, x= 1
g. 4x^2 + 4x= 0 ; 4x( x + 1) = 0; x = 0, x = -1
h. -x^2 + x = 0; -x(x - 1)= 0; x = 0, x = 1
Answer:
and
Step-by-step explanation:
We have to solve the given equation - 2x² + 3x - 9 = 0
To solve the equation given above we have to factorize the left-hand side of the equation.
But it can not be factorized. So, use the Sridhar Achaya formula.
Therefore,
and
So,
and
{Where
}
Therefore, the solutions are imaginary numbers. (Answer)
Note: The Sridhar Acharya Formula gives if ax² + bx + c = 0, then the roots of the equation are
and
.
