1) При m = -2:
4m-(m+3)^2+(m-3)(m+3)= 4(-2)-(-2+3)^2+(-2-3)(-2+3)= -8-1+5= -4
Ответ: -4
2) При m = 4:
4m-(m+3)^2+(m-3)(m+3)= 4(4)-(4+3)^2+(4-3)(4+3)= 16-(7)^2+1(7)= 16-49+7= -26
Ответ: -26
3) При x = -0,1:
(3x+4)^2-10x-(x-4)(4+x)= (3(-0,1)+4)^2-10(-0,1)-(-0,1-4)(4-0,1)= (0,3+4)^2+1-(3,9)(-3,9)= 4,3^2+1-13,41= 18,49+1-13,41= 6,08
Ответ: 6,08
4) При k = -1/2:
2(k-7)(k+5)-(k-5)^2-(k-7)(7+k)= 2(-1/2-7)(-1/2+5)-(-1/2-5)^2-(-1/2-7)(7-1)= 2(-7,5)(4,5)-(-5,5)^2-(-7,5)(-6,5)= 2(-33,75)-30,25-48,75= -67,5-30,25-48,75= -146,5
Ответ: -146,5
5) При a = -1/5:
(a+3)^2+(a-3)(3+a)-2(a+2)(a-4)= (-1/5+3)^2+(-1/5-3)(3-1/5)-2(-1/5+2)(-1/5-4)= (2,8)^2+(-3,2)(2,8)-2(1,8)(-4,2)= 7,84-8,96-15,12= -16,24
Ответ: -16,24
1) При m = -2:
4m-(m+3)^2+(m-3)(m+3)
= 4(-2)-(-2+3)^2+(-2-3)(-2+3)
= -8-1+5
= -4
Ответ: -4
2) При m = 4:
4m-(m+3)^2+(m-3)(m+3)
= 4(4)-(4+3)^2+(4-3)(4+3)
= 16-(7)^2+1(7)
= 16-49+7
= -26
Ответ: -26
3) При x = -0,1:
(3x+4)^2-10x-(x-4)(4+x)
= (3(-0,1)+4)^2-10(-0,1)-(-0,1-4)(4-0,1)
= (0,3+4)^2+1-(3,9)(-3,9)
= 4,3^2+1-13,41
= 18,49+1-13,41
= 6,08
Ответ: 6,08
4) При k = -1/2:
2(k-7)(k+5)-(k-5)^2-(k-7)(7+k)
= 2(-1/2-7)(-1/2+5)-(-1/2-5)^2-(-1/2-7)(7-1)
= 2(-7,5)(4,5)-(-5,5)^2-(-7,5)(-6,5)
= 2(-33,75)-30,25-48,75
= -67,5-30,25-48,75
= -146,5
Ответ: -146,5
5) При a = -1/5:
(a+3)^2+(a-3)(3+a)-2(a+2)(a-4)
= (-1/5+3)^2+(-1/5-3)(3-1/5)-2(-1/5+2)(-1/5-4)
= (2,8)^2+(-3,2)(2,8)-2(1,8)(-4,2)
= 7,84-8,96-15,12
= -16,24
Ответ: -16,24
