5x²-ax+2 is 3.
Then find
The value of
a.​

Answer 1

$question = 5 {x}^{2} - ax + 2 \\ zeroes \: of \: the \: polynomial \: is \: 3 \\ then \: find \: the \: value \: of \: a \: . \\ \\ solution \\ 5 {x}^{2} - ax + 2 = 0 \\ 5(3) {}^{2} - a(3) + 2 = 0 \\ 5(9) - 3a + 2 = 0 \\ 45 + 2 = 3a \\ 47 = 3a \\ \frac{47}{3} = a \\ \small\green{a = 15. \bar6 \: answer} \\ \\ \\ \small\red{\boxed{\boxed{it's ᭄亗 乄 ＭꫝղᎥនh 乄 亗✯❤࿐}}}$
