Answer:
$90-$70=$20
Step-by-step explanation: U take 90 from 20
The answer is 10(t-1) (5t+3).
An algebraic equation of the second degree in x is a quadratic equation. Typically, a quadratic equation is expressed in standard form as,.
And the factor is a number or algebraic expression that divides another number evenly without leaving any remainder.
To factor the given quadratic equation, first, take the common factor of the equation. Therefore,
Using the sum-product pattern, we can write 2t as 3t-5t. Therefore,
Now, find the common factor between the pairs within the bracket. We get,
Finally, rewriting the above terms by factoring out the greatest common factor, we get,
