Solve the quadratic equation 2x2 − 9x = 35 for x

or

Step-by-step explanation:

The given equation in standard form can be written as

comparing with the standard equation ,

we observe that

 ,    ,  

putting the values of a, b and c in the quardatic formula

x=(-b±)÷2a

x=(-(-9)±)÷2(2)

x=(9±)÷4

x=(9±)÷4

x=(9±19)÷4

x=(9+19)÷4  or x=(9-19)÷4

x=28÷4     or x=-10÷4

x=7   or x=-5÷2

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
