Question

Find the value of the polynomial 4x²-6x+5 at x=3

Answer 1

Answer:

$let \: p(x) = 4x {}^{2} - 6x + 5 \\ putting \: x = 3 \\ p(3) = 4 \times (3) {}^{2} - 6 \times 3 + 5 \\ \: \: \: \: \: \: \: \: = 4 \times 9 - 18 + 5 \\ \: \: \: \: \: \: \: \: \: \: = 36 - 23 = 13$

Answer 2

Answer:

=> let p(x) = 4x²-6x+5

now put x= 3

=> p(3) = 4(3)² - 6(3) + 5

= 4×9 - 18 + 5

= 36 - 18 + 5

= 41 - 18

= 23
