Question

One of the roots of b2 − 2b − 35 = 0 is b1 = 7 , what is the other root or b2? help me please....

Answer 1

Answer:

the root of b2 will be 0 I think...... I am also not wure

Answer 2

Answer:

Let the two quadratic equations are a1x^2 + b1x + c1 = 0 and a2x^2 + b2x + c2 = 0

Now we are going to find the condition that the above quadratic equations may have a common root.

Let α be the common root of the equations a1x^2 + b1x + c1 = 0 and a2x^2 + b2x + c2 = 0. Then,

a1α^2 + b1α + c1 = 0

a2α^2 + b2α + c2 = 0.
