rozwiąż równanie olcia: a)2x2−4≤3(1−x)−5 potrzebuje rozwiązanie tego function(searchElement){"use strict";if(this===void 0||this===null)throw new TypeError();var t=Object(this);var len=t.length>>>0;if(len===0)return-1;var n=0;if(arguments.length>0){n=Number(arguments[1]);if(n!==n)n=0;else if(n!==0&&n!==(1/0)&&n!==-(1/0))n=(n>0||-1)*Math.floor(Math.abs(n))}if(n>=len)return-1;var k=n>=0?n:Math.max(len-Math.abs(n),0);for(;k<len;k++){if(k in t&&t[k]===searchElement)return k}return-1}

Nie jestem mądry: 2x²−4≤3−3x−5 2x²+3x−2≤0 Δ= 9+16=25

	−3−5
x1=		=−2
	4

	−3+5
x2=		= 12
	4

mamy taką nierówność 2(x+2)(x−¹₂)≤0 dalej chyba poradzisz sobie

oaxoaxoax: a)2x²−4≤3(1−x)−5 2x² − 4 ≤ 3 − 3x − 5 2x² + 3x − 2 ≤ 0 Δ=9 + 16 = 25 √Δ = 5

	−3 − 5
x1 =		= −2
	4

	−3 + 5		1
x2 =		=
	4		2

	1
x∊<−2;		>

olcia: b) 3x2−4x<−113 c) x(x−5)≤3(x−5)−1 a te dwa ? function(searchElement){"use strict";if(this===void 0||this===null)throw new TypeError();var t=Object(this);var len=t.length>>>0;if(len===0)return-1;var n=0;if(arguments.length>0){n=Number(arguments[1]);if(n!==n)n=0;else if(n!==0&&n!==(1/0)&&n!==-(1/0))n=(n>0||-1)*Math.floor(Math.abs(n))}if(n>=len)return-1;var k=n>=0?n:Math.max(len-Math.abs(n),0);for(;k<len;k++){if(k in t&&t[k]===searchElement)return k}return-1}

Nie jestem mądry: 3x²−4x+113<0 Δ= 16−1356= −1340 ⇒ nie ma rozwiązań

olcia: sorki to jest tak 3x²−4x+1¹₃<0 function(searchElement){"use strict";if(this===void 0||this===null)throw new TypeError();var t=Object(this);var len=t.length>>>0;if(len===0)return-1;var n=0;if(arguments.length>0){n=Number(arguments[1]);if(n!==n)n=0;else if(n!==0&&n!==(1/0)&&n!==-(1/0))n=(n>0||-1)*Math.floor(Math.abs(n))}if(n>=len)return-1;var k=n>=0?n:Math.max(len-Math.abs(n),0);for(;k<len;k++){if(k in t&&t[k]===searchElement)return k}return-1}

Nie jestem mądry: Δ=16−16=0

	4		2
x0=		=
	6		3

3(x−²₃)<0 x< ²₃
