Answer:

(-5, -28)

Step-by-step explanation:

[tex]f(x) = {x}^{2} + 10x - 3[/tex]

[tex] = f(x) = {1x}^{2} + 10x - 3[/tex]

= a = 1, b = 10

[tex] = x = \frac{10}{2 \times 1} [/tex]

[tex] = x = - \frac{10}{2} [/tex]

= x = -5

[tex] = f(x) = {x}^{2} + 10x - 3..x = - 5[/tex]

[tex] = f( - 5) = - 28[/tex]

= (-5, -28)
