Step-by-step explanation:
Yes it is a quadratic equation
5x^2 + 40x = -7
5x^2 + 40x + 7 = 0
a = 5
b = 40
c = 7
-40/10 <u>+</u> (sqrt(1600 - 4(5)(7)))/10
-4 <u>+</u> (sqrt(1600-160))/10
-4 <u>+</u> (sqrt(1440))/10
-4 <u>+</u> 12(sqrt(10))/10
-4 <u>+</u> 6/5(sqrt(10))
Answer:
90
Step-by-step explanation:
make sure to use BIDMAS
start of by working out everything in the brakets first.
the first bracket would be 50
the second bracket would be -40
the minus these as there is a minus between the brackets
