Question

If a = 3, then find the value of a² + 3a – 8​

Answer 1

Given that the value of a = 3

We have to find the value of a from the equation,

$\bold{a^2+3a-8}$

Simply substitute the value of a in the equation

$\implies\bold{(3)^2+(3\times3)-8}$

$\implies\bold{9+9-8}$

$\implies\bold{18-8}$

$\boxed{\bold{\therefore\:a^2+3a-8=10}}$
