Question

find values of polynomial (3x) (4x – 5) + 3 ; for x = 3 *​

Answer 1

$\huge\rm\underline\blue{Given࿐}$

$\huge\fbox\red{x = 3}$

$\huge\rm\underline\blue{To find࿐}$

$\huge\fbox\red{(3x) (4x - 5) + 3}$

$\huge\rm\underline\blue{Solution࿐}$

$(3x)(4x - 5) + 3 \\ \\ = 3 \times 3 \times (4 \times 3 - 5) + 3 \\ \\ = 9 \times (12 - 5) + 3 \\ \\ = 9 \times 7 + 3 \\ \\ = 63 + 3 \\ \\ = 69$

$\huge\fbox\red{final answer = 69}$
