we have given a = 4

and an equation a²+4a -3

To find

we have to substitute a in the Equation a²+4a-3 and hence find the value.

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

The above Equation is in the form of a quadratic

as higest power is 2.

Step by step explanation:

1. First we write the equation in its normal form and if it is simplify then make it otherwise simply put the variable's value into the given equation we get the required value .

=>a²+4a-3

=>(4)²+4(4)-3

=>4×4+4×4-3

=>16+16-3

=>32-3

=>29

Hence ,the value of a²+4a-3 is 29
