9t 2 −12t+4.

It looks like you have a quadratic expression. The expression you provided is: \[ 9t^2 - 12t + 4 \] If you would like to factor this expression, we can look for two numbers that multiply to \( 9 \times 4 = 36 \) (the product of the leading coefficient and the constant term) and add to \(-12\) (the coefficient of the linear term). The two numbers that satisfy these conditions are \(-6\) and \(-6\). This allows us to rewrite the expression: \[ 9t^2 - 6t - 6t + 4 \] Now, we can group the terms: \[ (9t^2 - 6t) + (-6t + 4) \] Factoring by grouping: \[ 3t(3t - 2) - 2(3t - 2) \] Now we can factor out \( (3t - 2) \): \[ (3t - 2)(3t - 2) \] So, the factorization of the expression is: \[ (3t - 2)^2 \] If you need further assistance or different operations (like finding roots, graphing, etc.), please let me know!
