Question

under what condition will ax^2+5x + 7=0 be a quadratic equation?

Answer 1

  Solve   ax2-5x-7  = 0 

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

We shall not handle this type of equations at this time.

Answer 2

Answer:

a ≠ 0

Step-by-step explanation:

Given : $ax^2+5x + 7=0$

Definition of quadratic equation : A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.

The given equation : $ax^2+5x + 7=0$ will remain quadratic under the condition when a ≠ 0

when we substitute a =0 the equation becomes linear .

So, the under the condition a ≠ 0 $ax^2+5x + 7=0$  will be a quadratic equation
