Respuesta :

If we use the quadratic formula, then
                a = [ -(-46) +/- √(-46)^2 - 4(2)(252) ] / (2(2)) 
                a = 9, 14
The answers to this question are a=9 and a=14

Answer:

[tex]\text{The solutions are 14 and 9}[/tex]

Step-by-step explanation:

Given the equation

[tex]2a^2-46a+252=0[/tex]

we have to find the solution of above equation by using quadratic formula.

Equation:[tex]2a^2-46a+252=0[/tex]

[tex]\text{Comparing above with standard equation }ax^2+bx+c=0\text{, we get}[/tex]

a=2, b=-46, c=252

By quadratic formula

[tex]a=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]a=\frac{-(-46)\pm \sqrt{(-46)^2-4(2)(252)}}{2(2)}[/tex]

[tex]a=\frac{46\pm \sqrt{100}}{4}[/tex]

[tex]a=\frac{46\pm 10}{4}[/tex]

[tex]a=\frac{56}{4},\frac{36}{4}[/tex]

[tex]\text{The solutions are 14 and 9}[/tex]
