Help!!! Find the zeros of the quadratic equation by factoring. x^2+4x-5=0

weqwewe [10]

Answer:

x = -5, 1

Step-by-step explanation:

To factor an equation, break the polynomial into two binomials which multiply to make it. Find two numbers that multiply to C and add to B from $ax^2 + bx + c$ .

-1 and 5 multiply to -5 and add to 4.

$x^2+4x-5 = (x+5)(x-1)$

The zeros are the factors set equal to 0 and solved.

(x+5) = 0

x=-5

(x-1) = 0

x=1

steposvetlana [31]

Answer:

$307.5.

Step-by-step explanation:

We have been given that Elena's aunt bought her a $150 savings bond when she was born.When Elena is 20 years old, the bond will have earned 105% in interest.

To find bond's value after 20 years we will add 105% of 150 to 150.

$\text{Bond's value after 20 years}=150+(\frac{105}{100}\times 150)$
