Hi everyone first post on here, having trouble solving this equation, as I'm getting a different answer from a equation calculator
Find the value of [math]k\, =\, 4\, -\, b^2\, +\, ac[/math] when [math]a\, =\, 0.25,\, b\, =\, -2.15,[/math] and [math]c\, =\, -0.9.[/math] Give your answer correct to two significant figures.
k = 4 - B2 + ac
K - AC= 4 - B2
K - AC + B2 = 4
4 = K - AC + B2
4 = K - AC + (-4.62225)
4 = K + 0.65 + (-4.6225)
4 = K - 3.97225
