Solution
604r2−4
Show Solution

Factor the expression
4(151r2−1)
Evaluate
r2×604−4
Use the commutative property to reorder the terms
604r2−4
Solution
4(151r2−1)
Show Solution

Find the roots
r1=−151151,r2=151151
Alternative Form
r1≈−0.081379,r2≈0.081379
Evaluate
r2×604−4
To find the roots of the expression,set the expression equal to 0
r2×604−4=0
Use the commutative property to reorder the terms
604r2−4=0
Move the constant to the right-hand side and change its sign
604r2=0+4
Removing 0 doesn't change the value,so remove it from the expression
604r2=4
Divide both sides
604604r2=6044
Divide the numbers
r2=6044
Cancel out the common factor 4
r2=1511
Take the root of both sides of the equation and remember to use both positive and negative roots
r=±1511
