Answer» Answer: hello dear here is your answer hope it HELPS you have a GREAT day Step-by-step explanation: multiply the 1st & 3rd variable= (-24). two numbers that equal -24 when multiplied& 2(middle variable) when added/subtracted= (6 & - 4) rewrite using the new “middle” terms... 1a² + 6a – 4a – 24 = 0 (1a² + 6a) – (4a – 24) = 0 a(a + 6) – 4(a+6) = 0 RULE- the terms in parenthesis have to MATCH- combine it(once) with outer terms (a – 4)(a + 6) = 0 a – 4 = 0 add 4 to both sides (opposite of subtraction/negative #) a – 4 + 4 = 0+4 a = 4 a + 6 = 0 a+6 - 6 = 0- 6 a = -6 solutions: 4, -6 |
