Question

4x square minus 5x plus 3 if x=1/2​

Answer 1

Answer:

${4x}^{2} - 5x + 3$

$x = \frac{1}{2}$

$4 { (\frac{1}{2}) }^{2} - 5 \times \frac{1}{2} + 3$

$4 \times\frac{1}{4}-\frac{5}{2}+3$

$1 - \frac{5}{2} +3 = 4 - \frac{5}{2}$

$\frac{8 - 5}{2} = \frac{3}{2}$

Answer 2

=4x2-5x+3 if x=1/2

=4(1/2)2 -5(1/2)+3

=4(1/4)-5(1/2)+3

=4/4-5/2+3

=-5/2+3

=-5+6/2

=1/2
