Answer:
a ^ 2 - b ^ 2 = ( a + b ) ( a - b ) where a = 4p and b = 3q.
( 4p + 3q ) ( 4p - 3q )
Answer:
-20
Step-by-step explanation:
Replace X by 3
f(3) = -2(3)^2+ (3)-5 = -20

Answer:
-3 1/2
Step-by-step explanation:
Put the argument where the variable is and do the arithmetic.
f(-1/4) = 2(-1/4) -3 = -1/2 -3
f(-1/4) = -(3 1/2)
Answer:
x + 6 = 33
Step-by-step explanation:
6 more than x means there's an increment in the value of x by addition of 6
x + 6 = 33
This leads to an algebraic linear equation. x is an unknown variable and can be solved for
we subtract 6 from both sides of the equation
x + 6 - 6 = 33 - 6
x = 27
Therefore, we can say 6 more than 27 is 33
So discriminant is being counted from that equation:
b^2-4ac = 36-36 = 0
As discriminant is 0, then there is just 1 root -> -b/2a = 6/2 = 3.
