Identify the a b and c values of the following quadratic expression 4x^2+5x=4

A is the 4

B is the 5

and C is also 4.

A is always the number in front of x^2. B is always the number i front of the normal x, and C is the number that is on the other side of the equal sign!

∠cbe and ∠deb are same-side interior angles.

i took the test

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
