Evaluate (4×+4)(7×-3)
Ghella [55]

Answer:

28x^{2} +16x-12

Step-by-step explanation:

(4x+4)(7x+3)

Apply FOIL method: (a+b)(c+d)=ac+ad+bc+bd

a=4x,b=4,c=7x,d=-3

=4x*7x+4x(-3)+4*7+4(-3)

Apply minus - plus rules

+(-a)=-a

=4*7xx-4*3x+4*7-4*3

Simplify 4*7xx-4*3x+4*7-4*3

4*7xx

Multiply the numbers: 4*7=28

Apply exponent rule: a^{b} *a^{c} =a^{b+c}

xx=x^{1+1}

=28x^{1+1}

Add the numbers: 1+1=2

=28x^{2}

4*3x

Multiply the numbers: 4*3=12

=12x

4*7x

Multiply the numbers: 4*7=28

=28x

4*3

Multiply the numbers: 4*3=12

=12

=28x^{2} -12x+28x-12

Add similar elements: -12x+28x=16x

=28x^{2} +16x-12

28x^{2} +16x-12
