\(-5x^2+16x-3\)
\(=-5x^2+15x+x-3\)
\(=-5x\left(x-3\right)+\left(x-3\right)\)
\(=\left(x-3\right)\left(1-5x\right)\)
16x - 5x^2 - 3
=x - 5x^2 + 15x - 3
=x(1-5x) + 3(5x-1)
=3(5x-1) -x(5x-1)
=(3-x)(5x-1)
\(-5x^2+16x-3=\left(-5x^2+15x\right)+\left(x-3\right)\)
\(=-5x\left(x-3\right)+1\left(x-3\right)\)
\(=\left(x-3\right)\left(-5x+1\right)=\left(x-3\right)\left(1-5x\right)\)
-5x2 + 16x - 3
= -5x2 + 15x + x - 3
= -5x( x - 3 ) + 1( x - 3 )
= ( x - 3 )( 1 - 5x )
