4 x 2 − 12 x + 9 Use the formula ( a + b ) 2 = a 2 + 2 ab + b 2 .

lhhalimamalikbolakal · Answer

**(** 2x - 3)² (squared) simplifies to 4x² - 12x + 9. 
 The Breakdown 
 (2x - 3)² = (2x - 3) × (2x - 3) 
 Using the FOIL method, which stands for First , Outer , Inner , Last , you multiply the terms as follows 
 First: (2x) × (2x) = 4x² 
 Outer: (2x) × (-3) = -6x 
 Inner: (-3) × (2x) = -6x 
 Last: (-3) × (-3) = 9 
 Collect the like term 
 4x² - 6x - 6x + 9 
 4x² - 12x + 9 
 (2x -3)²= 4x² - 12x + 9.

lhhalimamalikbolakal · Answer

The expression $(2x - 3)^{2}$ simplifies to \( 4x^{2} - 12x + 9. \ This is achieved by using the FOIL method to expand the squared binomial. Step-by-step multiplication of terms leads to the final simplified form.
