Question

Find the value of y if x= -3 for the following equation: y=2x²+3x-5​

Answer 1

$\huge\red{Answer}$

$y = 2 {x}^{2} + 3x - 5 \\ x = - 3 \\ y = 2( { - 3)}^{2} + 3( - 3) - 5 \\ y = 2(9) - 9 - 5 \\ y = 18 - 14 \\ y = 4$

Answer 2

$\bf Find \: the \: value \: of \: y, \: if \: \: x = - 3 \\ \bf for \: the \: following \: equation : \\ \bf y = {2x}^{2} + 3x - 5$

$\huge\color{navy}{\textbf{\textsf{Answer:}}}$

$\bf When \: x = - 3, \: we \: get : \\ \bf y = {2( - 3)}^{2} + 3( - 3) - 5 \\ \bf y = 2(9) + ( - 9) - 5 \\ \bf y = 18 - 9 - 5 \\ \bf y = 18 - 14 \\ \bf y = \underline{ \underline{4}}$
