Question

pls help me too solve this ARMLINKS ​

Answer 1

If x = - 2

Then,

3x² - 5x + c = 19

Now, put x = - 2 According to the question,

3(-2)² - 5(-2) + c = 19

3(4) + 10 + c = 19

12 + 10 + c = 19

22 + c = 19

c = 19 - 22

c = - 3

I hope it helps you..

Answer 2

EVALUTION★

$= 3x {}^{2} - 5x + c = 19 - - (1)$

• when
• $x = - 2$

• x value put on eq (1)

• $= > 3( -2 ) {}^{2} - 5( - 2) + c = 19 \\ \\ \\ = > 3 \times 4 + 10 + c = 19 \\ \\ \\ = > 12 + 10 + c = 19 \\ \\ \\ = > c = 19 - 22 \\ \\ \\ = > c = - 3$
