Question

Comparing with
${a}^{2} + bx + c \\ \\ \\ \: {2x}^{2} - 11x + 9 \\ \\ {4y}^{2} - 7y + 3 \\ \\ {5a}^{2} + 6a - 8$
​

Answer 1

Step-by-step explanation:

We have to compare all the given equations with the standard equation

$a {x}^{2} + bx + c$

$1) \: 2 {x}^{2} - 11x + 9 \\ \\ on \: comparing \: with \: standard \: equation \\ \\ a = 2 \\ \\ b = - 11 \\ \\ c = 9$

$2)4 {y}^{2} - 7y + 3 \\ \\ on \: comparing \: with \: standard \: equation \\ \\ a = 4 \\ \\ b = - 7 \\ \\ c = 3$

$3)5 {a}^{2} + 6a - 8 \\ \\ on \: comparing \: with \: standard \: equation\\ \\ a = 5 \\ \\ b = 6 \\ \\ c = - 8$

Hope it helps you.
