Question

pls answer this question​

Answer 1

Step-by-step explanation:

4x - 3y^2 - 5xy. (x = -1 & y = 3)

4(-1) - 3(3)^2 - 5(-1)(3)

-4 -27 + 15

-4 -12

-16 ans...

Answer 2

${\bold{\underline{\underline{Answer:}}}}$

${\bold{\therefore 4x-3y^{2}-5xy=-16}}$

${\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\underline \bold{Given : } \\ \implies x = - 1 \\ \\ \implies y = 3 \\ \\ \underline \bold{To \: Find : } \\ \implies 4x - 3 {y}^{2} - 5xy = ?$

• According to given question :

$\bold{Putting \: the \: given \: values : } \\ \implies 4x - {3y}^{2} - 5xy \\ \\ \implies 4 \times - 1 - 3 \times { 3}^{2} - 5 \times (- 1 )\times 3 \\ \\ \implies - 4 - 3 \times 9 + 15 \\ \\ \implies - 4 - 27 + 15 \\ \\ \implies - 4 - 12 \\ \\ \implies - 16$
