Complete the equation so that it has solutions of –5 and 7. x2 x = 0
Pavlova-9 [17]

The equation it has solutions of –5 and 7  is x^2-2x-37=0

We have equation

solutions of equation are –5 and 7.

We have to find complete the equation.

We have given that solutions of the equation are -5, 7.

The standard form of a quadratic equation.

<h3>What is the factor of the quadratic equation?</h3>

(x -\alpha) (x- \beta)

Where we have

p = -(\alpha+\beta)  and q = (\alpha\times \beta)

So, roots are

( x- (-5)) (x-7)

p = -( -5+7) , q =(-5)(7).

p = -2  and q = -35.

On substituting p and q in equation

x^2+(-2)x-37=0

x^2-2x-37=0

Therefore,x^2-2x-37=0  is the equation of solution -5,7.

Chris withdraws $7.50 per week from his savings account. After 15 weeks, the balance in the account is $585.
slava [35]
Y-585 = -7.5(x-15)

y = -7.5x - 7.5(-15) + 585
y = -7.5x + 697.50

C = -7.5(52) + 697.50 = $307.50
