Question

12xpower2-15x+3 put x= 1/2 ​

Answer 1

Answer:

Given , x = 1 / 2

and

The polynomial , 12x^2 - 15x + 3

so

$12 {x}^{2} - 15x + 3 \\ \\ = 12 { (\frac{1}{2} )}^{2} - 15( \frac{1}{2} ) + 3 \\ \\ = 12 (\frac{1}{4} ) - \frac{15}{2} + 3 \\ \\ = \frac{12}{4} - \frac{15}{2} + 3 \\ \\ = \frac{12 - 30 + 12}{4} \\ \\ = \frac{24 - 30}{4} \\ \\ = \frac{ - 6}{4} \\ \\ = \frac{ - 3}{2} \\ \\ = - 1.5$

hope it helps uh ✔

Answer 2

12x²-15x+3

12(1/2)²-15(1/2)+3

12×1/4-15×1/2+3

12/4-15/2+3

12-30+12/4

24-30/4

-6/4

-3/2
