Answer:
x=4.3, x=-0.3
Step-by-step explanation:
4x^2-16x-26=-21
add 21 to both sides
4x^2-16x-26+21=-21+21
simplify
4x^2-16x-5=0
solve using the quadratic formula
a=4, b=-16, c=-5
x=-(-16)±√(-16)^2-4·4(-5)/2(4)
(solve using a calculator or using order of operations)
(solve for both - and +)
x=4.3, x=-0.3
Answer:
or
Step-by-step explanation:
Add 21 on both sides.
