Quadratic Formula = -b +- √b²- √4ac all over 2a

2w² - 28w = -98
+98 +98
2w² - 28w + 98 = 0

The equation has to be set to ax² + bx + c = 0 in order to use the quadratic formula.
= - (-28) +- √(-28)² - √4(2)(98) ÷ 2(2)
= 28 +- √784 - √784 ÷ 4
= 28 +- 0 ÷ 4
= 28 ÷ 4
= 7

There is only one solution because the discriminant is 0.

fiasKO [112]

Answer:

I think it's 2x/4 (1x/2 if simplified). if it's multiple choice that's what I'd go with and if that answer is wrong then sorry

Step-by-step explanation:

x•2 is 2x because you don't know the value x and you still have to divide by four. when simplified, 2/4 is 1/2 so it'd be 1x/2
