Answer 2

Hey there !!


▶ Question :- Find the value of p(x) = 5x² - 3 + 7 .


▶ Given point, x = -2 .


▶ Solution :-

The given equation is :-

p(x) = 5x² - 3 + 7 .

Now, put the value of x in the equation.

=> p(-2) = 5( -2)² - 3 + 7 .

[ Now, do the square of -2 ,i.e., (-2) × (-2) = 4 { - - = + } ]

=> p( -2) = 5 × 4 + 4 .

[From adding we get ]

= 20 + 4.

= $\boxed{24.}$


✔✔ Hence, it is solved ✅✅.
