Answer:
D: x=1
Step-by-step explanation:
Answer:
4y^2-6y+24
Step-by-step explanation:
add like-terms with polynomials (Khan Academy) had really good videos on specific examples
look ar the photo, x is 4
F( x ) = ( x - 1 ) ( x + 2i )( x - 2i ), because the zeroes are 1, -2i, +2i ;
f( x ) = ( x - 1 )( x^2 - 4i^2 ) = ( x - 1 )( x^2 + 4 ) = x^3 - x^2 + 4x - 4 ;
